It would be nice if a few large exchanges seized some large Russian owned accounts.
A) Funds are Frozen
B) btc /crypto loses no credibility as exchanges did it ie: no keys no coins
C) Eth could seize all coins since Eth is centralized and follows a single leader hmm sounds a bit like Putin.
Not sure I would call that "nice", there is no reason to hold the Russian citizens responsible for an action that was taken by a single man, it's not like Putin cares about the suffering of his own people, so by doing so, you are only making life harder for people who are already suffering, the folks in charge will not be affected by all of that.
I am thinking about appealing all the major miner hardware manufacturers and pool operators to stop trading and co-operating with Russian operators, until the Russian government stops the war crimes in Ukraine and also stops threatening Finland, Sweden and other western countries.
All the mining gears manufacturers are owned by the Chinese, China is siding Russia, it is extremely unlikely that they would do anything that could remotely piss the Chinese government off (of course, this assumes the unlikely fact that Bitmain and the likes of it are willing to lose a single client of theirs in the first place).
It might make more sense to boycott Chinese products "including mining gears" and somehow put pressure on China rather than doing the opposite, but again, will any of us or the large U.S players stop mining to a Chines pool or stop buying Chinese products for the sake of Ukraine?
I believe the best thing miners can do is use crypto to donate to whichever side they support (I hope we all agree that not all of us are against this invasion in the first place).
Lastly, may God protect the innocent people of Ukraine and every other nation.
