If you look at the US national debt, you'll see that right now it's at $31.2 Trillion. That's $93,860 for every single person in America.
Currently, 1 Bitcoin is traded at roughly $16k.
Even if you put together all the 21M Bitcoins that will ever be in existence at the ATH price, that wouldn't be enough to pay the US debt. You would be about $30 Trillion short.
