A judge in the U.S. District Court for the Southern District of Florida has reopened a case involving cryptocurrency startup Coinbase and the now-defunct exchange service Cryptsy.

Cryptsy collapsed in early 2016 amid allegations of fraud and mismanagement and claims that it had been hacked and subsequently drained of its funds. That decline – preceded by months of growing complaints about withdrawals and access to customer money – sparked a class action lawsuit that ultimately led to an $8.2 million judgment against Cryptsy's CEO, Paul Vernon.

In December 2016, a lawsuit was filed against Coinbase by the Cryptsy class-action investors, alleging that Coinbase should have prevented Vernon from funneling their money through the startup's service.

Coinbase sough to argue that those customers are bound by the arbitration agreement Vernon signed, but US District Judge Kenneth Marra – who is overseeing the case in Florida – disagreed. Two other appellate courts subsequently sided against Coinbase, leading to Marra's June 4 order to reopen.

The plaintiff's motion to reopen the case indicated that Coinbase did not oppose the move.

"Prior to filing this Motion, the undersigned counsel conferred with Defendant's counsel, and has been authorized to represent that Defendant does not oppose the relief sought herein," the document states.

On June 1, both the plaintiffs' and defendant's counsel held a case management conference via phone and will submit a report and proposed schedule order before the end of the week.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Here are the winners and losers (so far) in bitcoin mining from Nvidia's $2B CoreWeave investment

Racks of mining machines.

Nvidia’s deepened partnership with CoreWeave raises pressure on bitcoin miners pivoting to AI infrastructure.

What to know:

  • Shares of most bitcoin miners who have shifted business plans to AI infrastructure fell after Nvidia announced a fresh $2 billion investment in CoreWeave.
  • One analyst says Nvidia’s deepening partnership with CoreWeave could divert GPU access and funding away from independent miners trying to pivot into AI and high-performance computing.
  • Core Scientific, which CoreWeave attempted, but failed, to acquire in 2025, is the only miner posting gains on Monday.
