The U.S. Treasury Department sanctioned crypto exchange Chatex for its alleged involvement in ransomware operations, the federal agency said in a Monday press release.

  • It is the second time that the U.S. Treasury Department has sanctioned a crypto exchange. Chatex “has facilitated transactions for multiple ransomware variants” and has provided “material support” to crypto over-the-counter exchange Suex, which is also associated with ransomware, the press release said.
  • In September, Suex was sanctioned by the Treasury Department for ransomware activities.
  • The Biden administration has launched a crackdown on ransomware and is trying to convince other governments to follow its lead. Crypto intelligence firm Chainalysis estimates that North American crypto addresses sent $131 million to ransomware-linked addresses between July 2020 and June 2021, more than double what Western Europe, the second hardest-hit region, sent.
  • The Treasury’s Office of Foreign Asset Control (OFAC) added Chatex to its “Specially Designated Nationals” list. Another three entities associated with Chatex were also added to the blacklist, including Izibits OU, Chatextech SIA and Hightrade Finance Ltd.
  • The list covers individuals working for governments involved in terrorism or drug trafficking, according to the Treasury Department. Being on the list means the individuals’ assets are blocked and U.S. citizens are barred from doing business with them.
  • Suex and Chatex share a co-founder, Egor Petukhovsky, and at one point, a holding company, Estonia-based Izibits OU, according to TRM Labs.
  • A separate Treasury Department announcement mentioned about 30 sanctioned crypto wallet addresses associated with Chatex.
  • Chatex operates a crypto exchange and wallet through a Telegram messaging bot.

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.

Polymarket and similar platforms are considered unlicensed gambling operators, leading to blocked access.

What to know:

  • Ukraine has no legal framework for Web3 prediction markets, and current legislation provides no recognition for such platforms.
  • Polymarket and similar platforms are considered unlicensed gambling operators, leading to blocked access.
  • Legal changes are unlikely in the near future, as Parliamentary revisions to gambling definitions are extremely improbable during wartime, leaving prediction markets in a legal deadlock.
