Good luck confiscating bitcoin like they confiscated gold. I unfortunately lost all my private keys in an unfortunate boating accident.
Oh, me too. I guess boating accidents happen quite often nowadays, or perhaps we 've been in the same accident.
Seriously though:
One can only imagine the US government will eventually "ban" Bitcoin like it banned Gold a few decades ago.
How exactly do you think they can bitcoin? I don't judge you, I ask for a reasonable way to do it. You will realise that one of the reasons why Bitcoin is superior to Gold is this. They can't confiscate Bitcoin like gold, unless of course they ban the internet everywhere on planet earth.
P.S Even if they ban internet on the planet, thanks to blockstream satellite (https://blockstream.com/satellite/), Bitcoin may survive.
