Major crypto trading platforms including Binance, OKX, and Bybit have started implementing bans on Russian residents from using non-Russian fiat currencies, as well as those with sanctioned bank accounts such as Tinkoff Bank and Sberbank. This move follows a stricter regulatory environment in Russia, prompting exchanges to restrict access to certain users while complying with local laws. While the exchanges continue to operate in the country, such restrictions may impact user activity and trading volumes.
