There are ways to exchange fiat for cryptocurrency without going through a regulated business. Bisq, localcryptos, coordinating over chat and meeting up IRL.

Good luck finding someone to trade crypto tokens with without burning up the planet as with all these tokens do.

By the time you found someone and agreed, the price would have dropped 30%.

You might as well use the existing system.

Ok. So there's a war on, and I make a public post online advertising that I have a bunch of cash and I'd like to meet up to facilitate a trade...

Did you check out the anonymity properties of Bisq and localcryptos?

[citation needed]? I only know that Binance and Kraken specifically spoken against blocking the country.

To be more specific: They did not speak out about blocking "the country" but about closing accounts and restricting access for all Russian citizens/residents. They are, however, complying with targeted sanctions of the individuals on the sanction list.

If the scope of the OFAC sanctions forces the exchanges to start blocking Russian passport holders and/or residents, that will change, of course.

Great, they can ban Russians when forced to anyway? So much for no censorship on crypto tokens even a South Korean crypto exchange has done it. [0]

We both know the writing is on the wall and crypto will end up being useless for Russian users.

While you may know this, I know otherwise. Time will tell which of us has the more predictive knowledge.
