I mean, Russia needs all the taxes it can get right now, really. The state of their country isn't the best, but it's slowly getting better as time progresses. Having a minor tax on cryptos would be beneficial, especially considering that there have been a ton of GPUs being bought up within their country and they did have a shortage at one point if I remember correctly.

I'm not a fan of taxes or regulations of any kind, but sometimes they can be valuable to countries. I personally think this is one of those instances where a country can benefit, especially if it is cryptos as a whole and not just one specific coin taking the heat, like Bitcoin previously.

Also most of the miners will likely not move. You don't realize some of the situations in Russia.
