"Prolly Nothing" except for employees of the ransomware industry. https://finance.yahoo.com/news/putin-law-prohibiting-crypto-payments-russia-125015139.html
Putin shields & protects Russia from American manipulations of the Russian economy & currency, ie. from the economic war the US carries against its adversaries. Forbidding crypto in Russia means supporting the Russian currency, the Rouble. I always believed that Bitcoin is a creation of the CIA, so they know how to crash it... Putin is a wise man, maybe the best Russian leader ever.
Russia has ~ 1.2% of the btc network's reachable nodes. Maybe it has a significant impact, most likely not. They're effectively rugged the ruble being a denominator. eg. making Ruble based crypto pairs non-desirable https://bitnodes.io/
This is good news for Russia. The west was dumb-enough to help them in this regard for months now. Keep up the good work Westerners! Aside from Western nations fucking themselves in the ass every-which-way they could manage with sanctions so far to date... what other level-of-stupidity of self-inflicted pain can the West deliver on themselves in some sort of hippie-tree-hugger way that is supposed to STOP the war in Europe?
gotta give them credit, when they see a scam they shut it down here? they encourage more of it . bet on it
If you were a BTC millionaire in Russia, you'd have to sell them against USD and buy Rubels. Which makes Rubels stronger. Does it have an impact? Certainly, but most likely a small one.
But it's decentralized!!!!!! Where's the whole "you can't stop Bitcoin crowd? The knights templar were decentralized too. How'd that work out? Bitcoin is not designed with adequate privacy and network robustness to overcome state actors.
