Russians can only trade cryptocurrencies on foreign platforms through Russian brokers, provided that these foreign platforms do not comply with international sanctions.The country's central bank will establish its own standards for foreign platforms that Russian brokers and investors can use. Lozgacheva noted that even trading cryptocurrencies abroad through Russian intermediaries is subject to foreign regulation, posing additional risks.

A test must be completed before trading, and qualified investors are not subject to the limit but must also undergo testing. Relevant restrictions will be included in the second reading version of the draft "Digital Currency and Digital Rights Law," with key provisions expected to take effect on July 1.

"On-chain detective" ZachXBT disclosed that the DSJ Exchange (DSJEX) / BG Wealth Sharing Ponzi scheme, involving over $150 million, collapsed last week.Under its leadership, actions were taken in collaboration with Tether, Binance security teams, OKX, and U.S. law enforcement agencies, resulting in approximately $41.5 million in funds being frozen, including $38.4 million frozen by Tether on May 4, and about $3.1 million frozen by other platforms.It is reported that the project has been operating since 2025, using "1.3%--2.6% daily returns" as a gimmick to attract users through referral commissions and tiered rewards. DSJ has been identified as a fraudulent trading platform, BG as a supporting investment organization, and the so-called CEO "Stephen Beard" is also a fictional character. Investigations show that the project team evaded regulation by frequently changing domain names and hot wallets, and promoted false trading signals through messaging applications. Before the collapse, the platform had suspended withdrawals and demanded users pay a 12% "tax" under the pretext of "upcoming IPO."In terms of fund flow, the involved addresses transferred assets through Tokenlon exchanges, cross-chain bridges (such as Bridgers, Butter Network), and stablecoin wrapping/unwrapping, ultimately flowing into addresses of multiple exchanges. Currently, 13 regulatory agencies from five continents have issued risk warnings regarding this project. Analysts believe that this incident once again highlights the critical role of cross-chain tracking and multi-party collaboration in combating cryptocurrency fraud.
