Russia still has a functioning economy, and it's currency problems are not of the same nature as those that plague crypto. In fact, Russia's monetary problems are different enough that even if they had crypto instead they would face similar issues trying to use it that they face with their dollars because of the way sanctions are applied. Crypto may have promise, but it simply doesn't completely solve the class of problems that some people want it to.

I hate to say it, but the ruble has more than recovered. It's up.

IMHO it's far to early to assess the economical fallout from Russia's historic blunder in Ukraine.

Is it?? Try buying some.

> Russia had a lot of dollars, and then suddenly they were worthless or disappeared

Yes, due to broad international sanctions orchestrated by the U.S. You're unwittingly supporting my point.

If Beijing or Washington ever get around to treating cryptocurrency as an existential threat, make no mistake the market will be crushed and you will lose everything.

This is always my reply to crypto-heads: if btc/eth/etc. become too inconvenient for the U.S. government, or interfere in some material way with currency policy, the government will simply declare crypto illegal or regulate it to the point of pain, and that's that.
