The reported Russian Central Bank rule bars individuals from transferring Bitcoin and other cryptocurrencies from regulated accounts to personal wallets, according to The Defiant and its post. Transfers to legally authorized foreign custodians are described as requiring a test and a risk notice, but the available report does not specify the test’s contents or the notice process. The Defiant separately reports that direct crypto trades between individuals must use authorized intermediaries starting July 1, 2027. The sources do not name the rule’s legal instrument or say when the personal-wallet restriction takes effect.
