Apparently it's not just BTC, they are targeting all 'Tokens' of value, and they expect to be able to open any type of wallet, device with an account holding $10k or above in 'tokens' They claim it's for money laundering and terrorism but in reality it's probably only another tax grab.

Going to the USA don't bring your wallets, devices etc if they have more than the allowable amount in that country.
The odd thing is that any bank account now most likely has access to over 10k if the account has it, do we not bring ANY devices in to the USA now? Or do we just not go there.
