No surprise for me. After all, Russia and China have been long allies for a long time, and cryptocurrency is illegal in China as well. I don't know if it's just me but because crypto is illegal in China, they want it to be banned in Russia as well. This decision isn't only coming from the authorities from Russia, but in China as well. Only my theory though.
Overall, crypto has been illegal in China and we've seen little to no effect on the whole crypto market, and Russia might be a huge market for crypto, but I don't think that this total crypto ban will have a significant effect towards the crypto market. After all, the popularity of cryptocurrency is just going up every single year, and I believe the adoption rate increases yearly as well.
