    Appeal from the United States District Court
    for the Southern District of Florida
    ________________________
    (June 29, 2021)
    Before LAGOA, ANDERSON, and MARCUS, Circuit Judges.
    MARCUS, Circuit Judge:
    The plaintiffs in this putative securities fraud class action filed a motion for
    class certification as early as they realistically could have, but the district court
    denied it as untimely. The plaintiffs did not miss any rule-based or court-ordered
    deadline for their class certification motion. Nor did their timing cause prejudice
    to any party. The case calendar effectively deprived them of any opportunity to
    conduct discovery in support of class certification. Under the circumstances of this
    case, including the near omnipresence of an automatic discovery stay imposed by
    the Private Securities Litigation Reform Act whenever a motion to dismiss is
    pending -- in effect for just under fifteen of the eighteen months between the initial
    complaint and the plaintiffs’ certification motion -- the district court’s timeliness
    holding was an abuse of discretion.
    The district court also erred when it denied certification on the alternative
    ground that the plaintiffs had not established an administratively feasible method
    for identifying class members. Rule 23 implicitly requires that a proposed class be
    2
    USCA11 Case: 20-10894        Date Filed: 06/29/2021    Page: 3 of 25
    ascertainable; that is, the class must be “adequately defined such that its
    membership is capable of determination.” Cherry v. Dometic Corp., 
    986 F.3d 1296
    , 1304 (11th Cir. 2021). But our recent decision in Cherry clarified that to
    meet this ascertainability requirement, the party seeking certification need not
    establish its ability to identify class members in a convenient or administratively
    feasible manner. Of course, considerations of administrative feasibility may still
    be relevant to Rule 23(b)(3)(D) manageability analysis. 
    Id.
    We therefore vacate the district court’s order denying the plaintiffs’ motion
    for class certification and remand for further proceedings.
    I.
    The real action in this appeal is found in its procedural history, but a bit of
    substantive background is in order. Riding the recent wave of enthusiasm for
    cryptocurrencies, Centra Tech, Inc. got off to a fast start. Centra Tech promised to
    market the Centra Wallet, a digital wallet for storing different kinds of
    cryptocurrencies, and the Centra Card, a Visa and Mastercard-backed debit card
    that would allow users to make everyday purchases with cryptocurrencies. To
    raise funds to develop these products, Centra Tech held an initial coin offering
    (“ICO”) between July 2017 and April 2018. The ICO involved the sale of Centra
    Tokens, which entitled the holder to certain rights related to Centra Tech -- in other
    words, Centra Tokens were securities similar to the stock sold at an initial public
    3
    USCA11 Case: 20-10894       Date Filed: 06/29/2021   Page: 4 of 25
    offering. Centra Tech enlisted the promotional services of longtime world
    championship boxer Floyd Mayweather Jr. and double-platinum-selling hip-hop
    producer DJ Khaled to publicize the ICO to potential investors. Apparently
    impressed, thousands of investors participated in the ICO to enable Centra Tech to
    raise $32 million.
    But Centra Tech’s fortunes -- and those of its investors -- soon crashed.
    Centra Tech, it turned out, had not been truthful with the ICO purchasers. For one
    thing, Visa and Mastercard had not actually signed on to support the Centra Card.
    Nor were Centra Tech’s digital currency holdings insured, despite assurances
    otherwise. Centra Tech also tried to boost its investor appeal by listing fake
    executives. Centra Tech personnel even fabricated a LinkedIn profile for the
    fictional “Michael Edwards,” who was supposedly a Harvard professor and Centra
    Tech co-founder. Centra Tech’s real-life founders, Sohrab Sharma, Raymond
    Trapani, and Robert Farkas pled guilty to criminal securities and wire fraud
    charges in the Southern District of New York; the SEC also sued them for
    securities fraud. See United States v. Sharma et al., No. 18-cr-340-LGS, ECF Nos.
    152, 427, 470 (S.D.N.Y.); S.E.C. v. Sharma et al., No. 18-cv-2909-DLC, ECF
    (S.D.N.Y.). The SEC action remains stayed pending final resolution of the
    criminal case (Trapani, who cooperated with the government, has not yet been
    sentenced).
    4
    USCA11 Case: 20-10894       Date Filed: 06/29/2021    Page: 5 of 25
    ICO investor Jacob Rensel filed the instant suit against Centra Tech and
    some of its principals in the Southern District of Florida on December 13, 2017.
    He alleged the sale of unregistered securities in violation of Sections 12(a)(1) and
    15(a) of the Securities Act of 1933 (15 U.S.C. §§ 77l(a)(1), 77o(a)). The
    defendants moved to dismiss on February 2, 2018, triggering an automatic stay on
    “all discovery and other proceedings” under the Private Securities Litigation
    Reform Act of 1995 (“PSLRA”). 15 U.S.C. § 78u-4(b)(3)(B) (“In any private
    action arising under this chapter, all discovery and other proceedings shall be
    stayed during the pendency of any motion to dismiss, unless the court finds upon
    the motion of any party that particularized discovery is necessary to preserve
    evidence or to prevent undue prejudice to that party.”).
    Rensel (together with Wang Yun He, who had been named co-lead plaintiff)
    moved for leave to file an amended complaint on May 29, 2018. On September
    25, 2018, the district court granted this motion and simultaneously denied the still-
    pending motion to dismiss as moot. Thus, the PSLRA automatic discovery stay
    lifted on September 25. But this pause was short lived. Rensel, together with He,
    Chi Hao Poon, King Fung Poon, Jae Lee, Mateusz Ganczarek, and Rodney Warren
    (the “Plaintiffs”) filed an amended class action complaint on October 9, 2018.
    They repeated the unregistered securities claims from the first complaint and added
    allegations of material misrepresentations in violation of Sections 10(b) and 20(a)
    5
    USCA11 Case: 20-10894       Date Filed: 06/29/2021    Page: 6 of 25
    of the Securities Exchange Act of 1934 (15 U.S.C. § 78j(b)) against Centra Tech;
    its founders Sharma, Trapani, and Farkas; its executives Steven Stanley, Steven
    Sykes, Allan Shutt, and Chase Zimmerman; and ICO promoters Mayweather and
    Khaled. Sykes, Mayweather, and Khaled moved to dismiss the amended
    complaint on December 21, 2018. The PSLRA stay therefore kicked in once again
    on that day. Other defendants filed motions to dismiss later: Stanley on January
    16, 2019 and Shutt on April 26.
    Earlier, on November 19, 2018, the district court had ordered the parties to
    advise whether they preferred a standard or expedited case schedule (with outlines
    of each attached to the order), or whether they had good reasons to request a more
    protracted schedule. The parties timely responded with a Joint Discovery Plan and
    Status Report. The defendants requested an extended schedule, in part because of
    the need for discovery related to class certification. Thus, the defendants proposed
    a schedule premised on the PSLRA stay expiring by March 20, 2019; this schedule
    suggested that the court impose a June 14, 2019 deadline for the Plaintiffs to file a
    motion for class certification. The Plaintiffs, in turn, opined that the court’s
    standard schedule would suffice “if cued from the time of the adjudication of all
    pending motions to dismiss and the filing of Answers by defendants,” but observed
    that the court needed to add a deadline for their class certification motion.
    Notably, the Plaintiffs also informed the district court that it would be
    6
    USCA11 Case: 20-10894      Date Filed: 06/29/2021    Page: 7 of 25
    “inappropriate and unfair” to commence the discovery schedule until after the
    PSLRA stay had been lifted. The district court did not follow up with a scheduling
    order adopting its own or any party’s proposed schedule; thus, the court never
    imposed a deadline for the Plaintiffs’ class certification motion.
    At the Plaintiffs’ request, the Clerk entered default against Centra Tech on
    January 31, 2019 for failure to appear. The district court granted Sykes’s,
    Mayweather’s, Khaled’s, and Stanley’s motions to dismiss in a May 1, 2019
    omnibus order. But Shutt’s motion to dismiss remained, and so, therefore, did the
    PSLRA stay.
    The Plaintiffs voluntarily dismissed their claims against Sharma, Trapani,
    Farkas, and Zimmerman on June 5, 2019, leaving Centra Tech and Shutt as the
    sole remaining defendants. On June 7, the district court ordered the Plaintiffs to
    advise the court whether they intended to pursue their claims against Shutt and to
    file a motion for default judgment against Centra Tech by June 20. The Plaintiffs
    voluntarily dismissed their claims against Shutt on June 7, and the district court
    denied Shutt’s motion to dismiss as moot (also on June 7). At long last, no
    motions to dismiss remained pending, and the PSLRA discovery stay lifted once
    and for all.
    As ordered, the Plaintiffs moved for default judgment against Centra Tech
    on June 13, 2019. That same day, the Plaintiffs moved to certify three subclasses
    7
    USCA11 Case: 20-10894       Date Filed: 06/29/2021    Page: 8 of 25
    of Centra Tech investors: those who had purchased Centra Tokens from Centra
    Tech during the ICO between July 23 and October 5, 2017; those who had done so
    between October 6, 2017 and April 20, 2018; and those who had purchased Centra
    Tokens on the open market. Centra Tech opposed the motion, claiming, among
    other things, that the named plaintiffs lacked standing and could not meet Federal
    Rule of Civil Procedure 23’s requirements for certification because they could not
    adequately represent the class and did not possess claims typical of the class
    members. It also argued that the Plaintiffs had waived their rights to bring a class
    action by signing agreements governing the sale of their Centra Tokens. Centra
    Tech, however, did not even suggest that the Plaintiffs’ motion for class
    certification should be denied because it was filed in an untimely manner.
    On September 16, 2019, the district court denied the motion to certify the
    three subclasses, offering two alternative grounds for its decision. First, the district
    court relied on Rule 23(c)(1)(A)’s requirement that a class be certified “at an early
    practicable time” to hold that the Plaintiffs’ certification motion -- filed eighteen
    months after the initial complaint and six months after the amended complaint --
    was untimely. The district court noted the absence of any excuse for the delay and
    concluded that the Plaintiffs had purposefully delayed until the certification motion
    “would be unopposed by a defaulting defendant.”
    8
    USCA11 Case: 20-10894       Date Filed: 06/29/2021    Page: 9 of 25
    Second, the court determined that the proposed subclasses failed to meet
    Rule 23’s implicit ascertainability requirement because the Plaintiffs had not
    proposed an administratively feasible method of identifying absent class members.
    Plaintiffs’ reference to the existence of a Centra Tech spreadsheet listing ICO
    investor information did not suffice, the district court reasoned, because the
    spreadsheet covered only a subset of the members of the first proposed subclass.
    Moreover, the Plaintiffs did not actually have this spreadsheet; they relied on
    filings in the criminal and SEC actions describing it. The court added that the
    Plaintiffs’ reference to transaction information recorded by cryptocurrency
    exchanges was insufficient because the Plaintiffs had not explained to the court
    how such an identification process might work.
    The Plaintiffs tried again on October 1, 2019 with a renewed motion for
    class certification. This time, they devoted substantial argument to both timeliness
    and ascertainability. They explained that they had been waiting to move to certify
    the class until the lifting of the PSLRA automatic discovery stay allowed them to
    conduct certification-related discovery. Regarding ascertainability, they proposed
    a new, narrowed class definition (all persons other than certain Centra Tech
    insiders who had purchased Centra Tokens as part of the ICO between July 23 and
    October 5, 2017), and provided an affidavit from an experienced claims
    administrator detailing a claims forms process for identifying class members. The
    9
    USCA11 Case: 20-10894        Date Filed: 06/29/2021    Page: 10 of 25
    district court denied the renewed motion because, in its view, the Plaintiffs had not
    adduced “new evidence, changed circumstances, or new information about the
    class members’ claims” sufficient to justify a renewed motion.
    Meanwhile, the parties had been litigating the Plaintiffs’ court-ordered
    motion for default judgment against Centra Tech, which the district court granted
    on December 13, 2019. The judgment ordered Centra Tech to pay damages to the
    named plaintiffs based on their Centra Token holdings, which ranged from $350.10
    in Rensel’s case to $2,672,864.54 for He. The district court denied Centra Tech’s
    motion for reconsideration on February 3, 2020. With judgment now final, the
    Plaintiffs timely appealed the interlocutory orders denying their initial and renewed
    motions for class certification.
    II.
    By now, it is abundantly clear that the district courts enjoy wide latitude in
    deciding whether or not to certify a class, and our abuse-of-discretion review of
    class certification orders is accordingly deferential. See, e.g., Hines v. Widnall,
    
    334 F.3d 1253
    , 1257 (11th Cir. 2003). Even so, this deference is not absolute. We
    will reverse as an abuse of discretion a class certification order that represents a
    clear error of judgment, including because the district court followed improper
    procedures or applied the law in an unreasonable or incorrect manner. See Little v.
    T-Mobile USA, Inc., 
    691 F.3d 1302
    , 1305–06 (11th Cir. 2012). Here, both of the
    10
    USCA11 Case: 20-10894            Date Filed: 06/29/2021       Page: 11 of 25
    district court’s alternative holdings denying the Plaintiffs’ initial motion for class
    certification -- on timeliness and ascertainability -- were abuses of discretion. We
    therefore vacate this order and remand for further proceedings. 1
    A.
    District courts have broad discretion to control their dockets and surely may
    deny class certification motions as untimely, such as when unreasonable delay
    causes prejudice to the opposing party. See McCarthy v. Kleindienst, 
    741 F.2d 1406
    , 1412 (D.C. Cir. 1984) (“[I]t was within the District Court’s broad discretion
    to rely upon the untimeliness of the class certification motion, and the unfavorable
    consequences caused by the delay, as grounds for denying certification.”). Under
    the circumstances of this case, however, the district court abused its considerable
    discretion in finding the Plaintiffs’ motion for class certification to be untimely.
    For just under fifteen of the eighteen months between the December 13, 2017
    filing of the initial complaint and the June 13, 2019 filing of the motion to certify,
    the PSLRA automatic stay rule prevented the Plaintiffs from conducting any
    discovery to support their motion for class certification.2 The Plaintiffs, on the
    1
    Accordingly, we do not address the propriety of the district court’s order denying the Plaintiffs’
    renewed motion for class certification.
    2
    Arguably, the PSLRA stay prevented the Plaintiffs even from filing a motion to certify without
    having first taken discovery. While some courts have interpreted the PSLRA stay of “all
    discovery and other proceedings” to cover only proceedings related to discovery, see Medhekar
    v. U.S. Dist. Ct. for the N. Dist. of California, 
    99 F.3d 325
    , 328 (9th Cir. 1996), others have
    interpreted “other proceedings” to include motions for class certification, see Winn v. Symons
    11
    USCA11 Case: 20-10894           Date Filed: 06/29/2021       Page: 12 of 25
    facts of this case, were entitled to conduct some discovery before moving for class
    certification. We have observed that district courts will “often . . . need to go
    beyond the pleadings and permit some discovery and/or an evidentiary hearing to
    determine whether a class may be certified.” Mills v. Foremost Ins. Co., 
    511 F.3d 1300
    , 1309 (11th Cir. 2008). It is not as if the district court considered this to be a
    case in which the propriety of certification was readily discernible from the
    pleadings. Indeed, it found that the class was not ascertainable precisely because
    the Plaintiffs had “failed to proffer any evidence that Centra Tech’s records would
    be useful to identify class members.” Given the chance, the Plaintiffs may have
    been able to obtain such evidence during class discovery. The PSLRA discovery
    stay did not permanently lift until June 7, 2019, just six days before the Plaintiffs
    filed their certification motion.
    With the stay in effect during the bulk of the action’s pendency, the
    Plaintiffs could not have moved for class certification any earlier than they did.
    Setting aside the swift six days it took the Plaintiffs to move after the denial of the
    final motion to dismiss (hardly a delay), the stay of all discovery applied except
    Int’l Grp., Inc., No. IP 00-0310-C-B/S, 
    2001 WL 278113
    , at *2 (S.D. Ind. Mar. 21, 2001). In an
    order confirming the PSLRA stay that came relatively late in the proceedings (on May 1, 2019),
    the district court in this case adopted a magistrate judge’s report interpreting the PSLRA stay to
    apply only to discovery-related proceedings. Our own Court has not directly addressed the scope
    of the PSLRA stay, and we need not and do not do so today. Even assuming that the narrower,
    discovery-only interpretation is correct, the operation of the PSLRA stay in this case effectively
    prevented the Plaintiffs from moving for class certification any earlier than they did.
    12
    USCA11 Case: 20-10894       Date Filed: 06/29/2021    Page: 13 of 25
    during two short windows: (1) one month and twenty days between the filing of
    the initial complaint and the motion to dismiss that complaint, and (2) one month
    and twenty-seven days between the grant of leave to amend the complaint and the
    filing of the motion to dismiss the amended complaint. The Plaintiffs could not
    feasibly have moved for class certification during these periods. The amended
    complaint added new securities fraud claims, while the initial complaint alleged
    only the sale of unregistered securities. In fact, a certification motion based on the
    updated allegations, now including claims of material misrepresentations in
    violation of the Securities Exchange Act of 1934, would have presented different
    issues than one based on the initial complaint. See Fed. R. Civ. P. 23(a), (b)(3)
    (requiring analysis of, among other things, whether “there are questions of law or
    fact common to the class,” whether “the claims or defenses of the representative
    parties are typical of the claims or defenses of the class,” and whether “questions
    of law or fact common to class members predominate over any questions affecting
    only individual members”).
    During both windows when the possibility of discovery briefly remained
    open, the Plaintiffs lacked even the benefit of the defendants’ answer, which would
    have informed a motion for class certification by responding to the factual
    allegations and specifying any affirmative defenses. See 
    id.
     Moreover, these short
    windows did not provide sufficient time to take certification-related discovery.
    13
    USCA11 Case: 20-10894         Date Filed: 06/29/2021    Page: 14 of 25
    Indeed, any certification motion brought during these early periods may well have
    been dismissed as premature. See, e.g., Lopez v. Glob. Credit & Collection Corp.,
    No. 17 CV 427, 
    2017 WL 4340098
    , at *2 (N.D. Ill. Sept. 29, 2017) (“The motion
    for class certification is premature—no factual development has occurred, no
    answer is on file, and plaintiff is not in a position to meet his burden to prove the
    viability of a class action.”); Dickerson v. Lab’y Corp. of Am., Inc., No. 8:14-CV-
    1390-T-30TBM, 
    2014 WL 12774194
    , at *1 (M.D. Fla. July 23, 2014) (certification
    motion was premature because it “was filed prior to a response from Defendant
    and prior to the commencement of discovery”); Hornsby v. McDonald’s USA,
    LLC, No. 8:14-CV-2288-T-30TBM, 
    2014 WL 12713358
    , at *1 (M.D. Fla. Oct. 7,
    2014) (same).
    Add to all of this that the Plaintiffs had no reason to believe they should
    have filed their class certification motion any earlier: the district court failed to set
    a deadline for filing the class certification motion. In response to the district
    court’s order, the parties timely filed a Rule 26(f) Joint Discovery Plan and
    Conference Report, but the district court did not enter a scheduling order. This
    omission was a violation of the Federal Rules of Civil Procedure and the Local
    Rules for the Southern District of Florida. Fed. R. Civ. P. 16(b)(1)(A) (“[T]he
    district judge . . must issue a scheduling order . . . after receiving the parties’ report
    under Rule 26(f) . . . .”) (emphasis added); S.D. Fla. L.R. 16.1(b)(3) (providing,
    14
    USCA11 Case: 20-10894          Date Filed: 06/29/2021       Page: 15 of 25
    with exceptions not relevant here, that “the Court shall enter a Scheduling Order as
    soon as practicable but in any event within sixty (60) days after the appearance of a
    defendant and within ninety (90) days after the complaint has been served on a
    defendant.”) (emphasis added). This deprived the Plaintiffs of any notice that their
    June 13, 2019 certification motion might be denied as untimely. There was no
    federal or local rule deadline for certification motions. The parties had every
    reason to believe that a June 2019 filing would be reasonable in this case; after all,
    the defendants’ proposed schedule contemplated a certification deadline of June
    14, 2019. And the district court said nothing to dispel this understanding. 3 See
    William B. Rubenstein, 3 Newberg on Class Actions § 7:5 (5th ed. Dec. 2020
    Update) (hereinafter “Newberg”) (“[I]n most cases, the court will address the
    timing of class certification at the initial case management conference[, which]
    often results in a timetable agreed upon by all of the parties setting out the
    deadlines leading to the class certification decision.”).
    3
    Given typical securities class action practices, it is not surprising that even the defendants
    thought an eighteen-month lapse between the initial complaint and filing a motion for class
    certification would be reasonable. In securities class actions filed between 2000 and 2018, the
    median time from the filing of the initial complaint to the class certification decision was two-
    and-a-half years. The time between the complaint and the certification decision was less than
    two years in only thirty percent of all cases and was less than one year in only four percent of
    cases. Stefan Boettrich & Svetlana Starykh, Recent Trends in Securities Class Action Litigation:
    2018 Full-Year Review (2019),
    https://www.nera.com/content/dam/nera/publications/2019/PUB_Year_End_Trends_012819_Fin
    al.pdf. The Plaintiffs’ motion to certify simply did not come late.
    15
    USCA11 Case: 20-10894            Date Filed: 06/29/2021       Page: 16 of 25
    Moreover, the parties’ understanding was reasonable in light of the general
    rules governing class action procedure. As we have explained, class action
    plaintiffs often require discovery to inform their class certification arguments, so it
    was perfectly reasonable for the Plaintiffs to believe they would not have to file
    their motion until some time after the lifting of the PSLRA discovery stay. Indeed,
    the defendants conditioned their suggested June 14, 2019 certification motion
    deadline on the expectation that the PSLRA discovery stay would lift by March 20.
    Federal Rule of Civil Procedure 23(c)(1)(A) previously required district courts to
    make a certification determination “as soon as practicable”; in 2003, the Rule was
    amended to require the district court to make a certification decision “at an early
    practicable time.” 7AA Charles A. Wright & Arthur R. Miller, Federal Practice &
    Procedure § 1785.3 (3d ed. Oct. 2020 Update). In part, this change sought to allow
    “more time for class discovery.” China Agritech, Inc. v. Resh, 
    138 S. Ct. 1800
    ,
    1807 (2018) (internal quotation marks and citation omitted). Thus, the current
    version of Rule 23(c)(1)(A) not only supports the expectation that plaintiffs will
    have some opportunity for discovery before moving for class certification; it also
    places the onus of ensuring a timely certification decision on the district court,
    rather than on plaintiffs. 4 Fed. R. Civ. P. 23(c)(1)(A) (“At an early practicable
    4
    The Southern District of Florida repealed its previous rule requiring class certification motions
    to be filed within 90 days of the complaint in order “to conform to the December 2003
    amendment to Federal Rule of Civil Procedure 23(c)(1)(A), which clarifies that a Court may
    16

    time after a person sues or is sued as a class representative, the court must
    determine by order whether to certify the action as a class action.”).
    To be sure, the Plaintiffs did not help themselves as much as they could
    have. They failed to mention the lack of any real opportunity for discovery in their
    certification motion or to move for limited relief from the PSLRA stay in order to
    conduct certification-related discovery, something they requested with respect to
    two other issues. But the district court was not without notice that the parties
    believed discovery was necessary to inform the class certification decision in this
    case. The joint Rule 26(f) report discussed the PSLRA stay and informed the court
    that discovery “would be significantly complicated by class certification issues,”
    including “hard-fought” disputes “related to proof of commonality and typicality.”
    Moreover, the Plaintiffs were not required to move for PSLRA stay relief in order
    to expedite the filing of a class certification motion; as we have discussed, it was
    not unreasonable for the Plaintiffs to simply wait for the PSLRA stay to expire
    before conducting class discovery and moving for certification.
    Yet the district court denied the Plaintiffs the chance to do this: on June 7,
    2019, the same day the PSLRA stay lifted upon the district court’s denial of the
    last remaining motion to dismiss, the court ordered the Plaintiffs to move for
    defer the decision on whether to certify a class if it is prudent to do so.” In re: Amendments to
    the Local Rules, Admin. Order 2011-11, at 54 (S.D. Fla. Nov. 29, 2011).
    17
    USCA11 Case: 20-10894            Date Filed: 06/29/2021       Page: 18 of 25
    default judgment against Centra Tech and Shutt, the only remaining defendants in
    the case, 5 by June 20. Thus, events forced the Plaintiffs’ class certification hand.
    If the district court entered final judgment against Centra Tech and disposed of the
    case before seeing a class certification motion, it would have deprived the
    Plaintiffs of their ability to obtain class certification and to pursue class-wide
    damages. Therefore, they had to either move for class certification without any
    supporting discovery or forgo the opportunity to move for class certification at all.
    The Plaintiffs might have improved their lot by requesting relief from the order to
    move for default judgment or, again, by mentioning their difficult position in their
    certification brief. Even so, despite our Court having previously concluded that
    discovery is “often” necessary before a class certification decision, Mills, 
    511 F.3d at 1309
    , the district court effectively required the Plaintiffs to move for class
    certification before they had any real chance to take any class discovery. It then
    denied certification based in part on a lack of evidence of ascertainability, which
    the Plaintiffs might have been able to address with the aid of discovery.
    All of this might have been within the district court’s ample discretion if
    there were any sound reasons for finding the certification motion to be untimely
    even in the absence of a deadline, but there weren’t. See Newberg § 7:7 (in
    deciding whether to accept a late certification motion, courts consider “the
    5
    Regarding Shutt, the Plaintiffs instead elected to dismiss their claims.
    18
    USCA11 Case: 20-10894        Date Filed: 06/29/2021    Page: 19 of 25
    circumstances causing the delay” and “whether the opposing parties have been
    prejudiced by the delay”). The district court noted that the Plaintiffs filed their
    motion eighteen months after the initial complaint and had provided “no excuse or
    justification for this delay.” But as we have explained, considering the posture of
    this case, the eighteen-month lapse was not a “delay” that required any
    justification. More troubling, the district court stated that “the Plaintiffs’ delay
    appears to be a deliberate decision to file the motion when it would be unopposed
    by a defaulting defendant.” Yet the record belies this conclusion. The Clerk
    entered default against Centra Tech on January 31, 2019, so if the Plaintiffs were
    indeed playing a delay-until-default game, there was no reason for them to wait
    until June to file their certification motion. The district court did not mention any
    other way in which the timing might have prejudiced the defendant; nor has Centra
    Tech cited any. Indeed, Centra Tech did not so much as raise timeliness as a
    reason for denying the Plaintiffs’ motion for class certification when it filed its
    response in opposition. Rather, Centra Tech argued that arbitration provisions
    barred the action, that the named plaintiffs lacked standing and could not meet the
    substantive requirements of Rule 23, and no more.
    In short, the Plaintiffs could not practically have moved for class
    certification any earlier than they did. Effectively, they had no choice but to move
    prematurely. The Plaintiffs did not miss any class certification deadline, and their
    19
    USCA11 Case: 20-10894       Date Filed: 06/29/2021    Page: 20 of 25
    timing did not prejudice any party. On this record, the district court’s denial of the
    Plaintiffs’ class certification motion as untimely was an abuse of discretion.
    B.
    The district court’s alternative holding on the Plaintiffs’ initial motion for
    class certification, that the proposed class was not sufficiently ascertainable, was
    also an abuse of discretion.
    In their motion, the Plaintiffs proposed the following three subclasses:
    (1) All persons and entities who purchased CTR Tokens directly from
    Defendant Centra Tech during Centra Tech’s official initial coin
    offering from approximately June 23, 2017 through October 5, 2017;
    (2) All persons and entities who purchased CTR Tokens directly from
    Defendant Centra Tech during the remainder of Centra Tech’s initial
    coin offering from approximately October 6, 2017 through April 20,
    2018; and
    (3) All persons and entities who purchased CTR Tokens on the open
    market as a result of Defendant Centra Tech successfully soliciting their
    purchases of CTR Tokens.
    Relying on our unpublished decision in Karhu v. Vital Pharms., Inc., 621 F. App’x
    945, 947 (11th Cir. 2015), the district court reasoned that the Plaintiffs had to
    demonstrate an “administratively feasible” method of identifying class members
    that was “manageable” and did “not require much, if any, individual inquiry.” The
    court held that the Plaintiffs could not meet this requirement merely by referring to
    a spreadsheet “that was provided to the government in the criminal case [against
    the founders of Centra Tech] which provide[d] information regarding over 3,500
    20
    USCA11 Case: 20-10894       Date Filed: 06/29/2021    Page: 21 of 25
    purchasers of Centra Tech Tokens.” The spreadsheet as described in the criminal
    complaint “would only partially cover one of the three subclasses” (the first ICO
    purchaser subclass), and there was no guarantee that the government would agree
    to share the spreadsheet with the Plaintiffs. Moreover, the district court reasoned
    that the “Plaintiffs [had] failed to proffer any evidence that [other Centra Tech]
    records would be useful to identify class members.” And their suggestion of
    drawing on information gleaned from currency exchanges did not help because
    “[t]he world of cryptocurrency and currency exchanges is a highly technical area
    and the Plaintiffs would need to explain to the Court how currency exchanges
    work, what information is stored, and how the Plaintiffs would access this
    information to identify potential class members.”
    The district court was right to inquire into whether the proposed subclasses
    were “adequately defined and clearly ascertainable” before it considered the
    express requirements of Rule 23(a). Cherry, 986 F.3d at 1302 (internal quotation
    marks omitted). But after the district court’s decision, we held in Cherry that
    “administrative feasibility is not a requirement for certification under Rule 23.” Id.
    at 1304. In fact, the words “administrative feasibility” are nowhere to be found in
    Rule 23. Cherry thus clarified that “a proposed class is ascertainable if it is
    adequately defined such that its membership is capable of determination.” Id. at
    1304. While Rule 23 implicitly requires that class membership must be
    21
    USCA11 Case: 20-10894       Date Filed: 06/29/2021    Page: 22 of 25
    ascertainable since a court cannot determine issues such as commonality or
    typicality if class membership is defined in vague terms, “membership can be
    capable of determination without being capable of convenient determination.” Id.
    at 1303. Administrative feasibility may be relevant to “the manageability criterion
    of Rule 23(b)(3)(D),” but that provision requires a “comparative” analysis that is
    incompatible with a threshold, standalone administrative feasibility requirement.
    Id. at 1304. The court must weigh any manageability concerns against the
    advantages of proceeding as a class action. Id. at 1304–05. We thus rejected
    Karhu’s requirement that a Plaintiff explain to the district court exactly how the
    class members can be identified in a convenient manner. Id.
    Plaintiffs’ proposed subclasses easily meet the Cherry standard for
    ascertainability. Membership in each of the subclasses turns on the objective,
    verifiable criterion of having purchased a particular security within a particular
    date range. The token purchaser spreadsheet identified many class members, and
    others could have been identified through additional Centra Tech ICO records or
    submission of claims forms verified by transaction records. Perhaps the third
    subclass, open market purchasers, would have presented some difficulty, but even
    so, the district court should have asked whether membership was “capable of
    determination” rather than rejecting the Plaintiffs’ arguments on this front simply
    because they had not explained precisely how they would access cryptocurrency
    22
    USCA11 Case: 20-10894            Date Filed: 06/29/2021         Page: 23 of 25
    exchange information to identify class members. Since application of an incorrect
    legal standard is an abuse of discretion, id. at 1300, the district court’s application
    of the Karhu heightened ascertainability standard cannot stand.
    Neither of the district court’s reasons for denying the Plaintiffs’ initial
    motion for class certification withstands abuse-of-discretion review. Accordingly,
    we VACATE the district court’s order denying the initial motion for class
    certification and REMAND for further proceedings consistent with this opinion.
    We also necessarily VACATE the final judgment. 6 We do not disturb, however,

    Even though the named plaintiffs have received a favorable judgment on their individual
    claims, there remains an ongoing controversy with respect to their asserted right to represent the
    interests of the proposed class. “Ordinarily, only a party aggrieved by a judgment or order of a
    district court may exercise the statutory right to appeal therefrom.” Deposit Guar. Nat. Bank v.
    Roper, 
    445 U.S. 326
    , 333 (1980). But this rule “does not have its source in the jurisdictional
    limitations of Art. III,” so, in certain circumstances, even a party who has prevailed on the merits
    in district court may appeal from an adverse collateral aspect of the judgment -- “so long as that
    party retains a stake in the appeal satisfying the requirements of Art. III.” 
    Id.
     at 333–34. Thus,
    in Roper, the Supreme Court held that named plaintiffs could appeal a district court’s order
    denying class certification even though the district court had entered final judgment awarding
    them damages on their individual claims. The defendants had tendered these amounts and the
    district court had entered judgment even though the named plaintiffs objected. 
    Id. at 330
    ; see
    also Microsoft v. Baker, 
    137 S. Ct. 1702
    , 1711 (2017) (plaintiffs met with a denial of class
    certification may “litigate[] the case to final judgment and then appeal[]” the adverse
    certification decision.).
    Like in Roper, the district court’s judgment in this case awarding damages on the named
    plaintiffs’ individual claims did not grant them relief regarding their “continuing individual
    interest in the resolution of the class certification question.” 
    445 U.S. at 336
    . At the very least,
    the named plaintiffs in this case retain an “individual interest in the resolution of the class
    certification question in their desire to shift part of the costs of litigation to those who will share
    in its benefits if the class is certified and ultimately prevails.” See id.; see also Love v.
    Turlington, 
    733 F.2d 1562
    , 1565 (11th Cir. 1984) (“[A] class action plaintiff presents two
    separate issues for judicial resolution: the claim on the merits, and the claim that he is entitled to
    represent a class.”). This concrete interest saves this case from mootness and is sufficiently
    23
    USCA11 Case: 20-10894            Date Filed: 06/29/2021        Page: 24 of 25
    the district court decisions not before us on appeal, such as its determinations about
    Centra Tech’s liability to the named plaintiffs. Roper, 
    445 U.S. at 336
     (appellate
    jurisdiction in an appeal of an order denying class certification is limited to the
    certification issue and does not extend to “the merits of the substantive
    controversy”). Nor do we express any view on the propriety of class certification
    in this case other than with respect to the timeliness and ascertainability holdings in
    this opinion.
    related to the named plaintiffs’ “personal stake in the appeal” to confer federal appellate
    jurisdiction. Roper, 
    445 U.S. at 336, 340
    ; see also Love, 
    733 F.2d at
    1564–65 (named plaintiff’s
    settlement of her individual claim did not moot her appeal from a denial of class certification);
    Eisenberg v. Gagnon, 
    766 F.2d 770
    , 784–85 (3d Cir. 1985) (holding there was “no bar” to named
    plaintiffs’ appeal of a class certification denial even though they had obtained individual relief on
    the merits in the form of a default judgment against one defendant and trial victories over others,
    because “at a minimum” they retained an interest in shifting litigation costs if a class ultimately
    prevailed), superseded by rule on other grounds as stated in Mielo v. Steak ‘n Shake Operations,
    Inc., 
    897 F.3d 467
    , 483 (3d Cir. 2018); cf. Hines, 
    334 F.3d at 1257
     (“Although [the named
    plaintiffs] all settled individual claims . . . they still have standing to appeal the denial of
    certification because the settlement agreement preserved their right to appeal the class
    certification decision.”). Importantly, the named plaintiffs moved for default judgment against
    Centra Tech only because the district court ordered them to do so; they did not, for example,
    consent to a defendant’s offer of judgment and waive their right to appeal. See Shores v. Sklar,
    
    885 F.2d 760
    , 762–63 (11th Cir. 1989).
    Thus, the district court’s judgment awarding damages on the named plaintiffs’ individual
    claims did not grant them relief regarding their claim that they are entitled to represent a class.
    In fact, the interlocutory orders denying class certification merged into the final judgment, see id.
    at 763, so the final judgment resolved this claim against the named plaintiffs. Put another way,
    the final judgment did not give them, and in fact denied a portion of the “complete relief” they
    requested. See Radha Geismann, M.D., P.C. v. ZocDoc, Inc., 
    909 F.3d 534
    , 543 (2d Cir. 2018).
    The named plaintiffs may, therefore, obtain reversal of the portion of the district court’s
    judgment precluding them from representing the putative class and continue to pursue class
    certification (and, if successful, merits relief on behalf of the class).
