I keep a lot of money in cryptocurrency in my cold wallets. Those can't be seized, no run on the banks there, and thus far the appreciation has been great.
That is, the addresses can be published by whatever entity with a threat to taint addresses they send value too unless the target addresses turn the value over to the government entity.
They can freeze your bank accounts too.
Also, hard to taint coins you don't realize exist. Not that I have any of those, mine are all from exchanges, but miners could easily have backup coins, as could OTC traders
