I would say so. However the thugs in USSA has what is called "civil asset forfeiture" where the burden of proof lies on the victim. What this means in practice is that you need to prove source of funds, that it is legal and accounted for. It's going to be tricky for many, given the nature of cryptocurrencies. Unless you have tracked every single transaction from A -> Z your "proofs" may not be enough.

It's likely you'll need to engage an expensive US lawyer as well, I kind of doubt they will open any sort of "claim" process. This is a very practical way to steal funds from low resource individuals or just unfortunate souls who's been enjoying the freedom of cryptocurrencies to not account for every step they make.
