Prosecutors detailed Danil Potekhin and Dimitrii Karasavidi’s alleged heists, victims and target exchanges in a 30-page forfeiture complaint filed Wednesday against the pair’s previously seized crypto funds.

  • Karasavidi and Potekhin allegedly “deployed” a series of bogus Poloniex, Gemini and Binance lookalike sites that duped unwitting users into sharing their login credentials, giving the hackers control of wallets.
  • They then “drained” $20 million worth of bitcoin , ether and NEO from victims’ accounts, according to the complaint. Prosecutors said the lion’s share ended up in Karasavidi’s Bitfinex account.
  • Other funds were frozen by Poloniex and quickly seized by authorities, who filed the lawsuit to take control of 15,602 ETH, 199.8 BTC, $6.1 million in cash and 1,199 NEO, a total worth $14.2 million at press time.
  • That ETH haul was actually the product of a separate hacker scheme: market manipulation, authorities say.

In late October 2017, hackers pumped $5 million of one victim’s crypto into NEO’s Gas market, skyrocketing the usually sleepy token’s value 13,000% before ordering their personal gas-holding Poloniex accounts to cash out into ETH. The victim “lost virtually all of his $5 million in cryptocurrency,” prosecutors alleged.

  • Prosecutors also claimed the hackers attempted to cover up the stolen crypto’s origin by “layering” funds – a classic money-laundering technique.
  • Treasury officials said they used “blockchain tracing analysis” to follow the ETH from the Poloniex manipulation and the Poloniex, Binance and Gemini phishing schemes into Karasavidi’s Bitfinex account.
  • They further claimed to have identified Potekhin as the owner of multiple misspelled Poloniex domain names linked to the phishing scheme.
  • Similar tactics were used against Binance and Gemini customers, the regulator said in the lawsuit.

Karasavidi and Potekhin face a mounting lineup of legal troubles. This week, they’ve been added to the Treasury Department’s OFAC blacklist and also face federal wire fraud, hacking and money laundering charges.

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.
