From August 1, the law will come into force, but CBDC won't work everywhere and it is not yet clear how this will work in practice.
I do not understand the idea of CBDC. The country does not want bitcoin to be legalized but since they see the people's interest in crypto coins, they decide to launch their own CBDCs. The government control CBDC with no control over the supply is a no threat to bitcoin.
I've been following this as well, and here's the first bad news. QIWI bank in Russia is often used to exchange cryptocurrencies for fiat and vice versa, it is very easy to get a bank card from them. Now the bank is under restrictions and under such conditions it is impossible to buy and sell cryptocurrencies.
