America is already bankrupt. They are trillions of dollars in debt and have no hope in hell of paying it back. Their only hope is to buy up loads of bitcoin and wait for them them to be worth a few million each. This will at least reduce it to a more manageable size
I'm wishing for the opposite, by buying up bitcoin it actually hasten the bankruptcy process. Because there is just too much bitcoin to buy and not to forget tons of other altcoins too.
I don't think what comes up in your mind that you want to bankrupt the country of the USA, this country is fully developed and they are the most powerful country among of all. So, bankrupt I think not in the country but probably people who in their(impossible to happen).
Getting born on a powerful country are itself very unfair, it is just same as getting born on a rich family, but you are not born on a rich family, your life gonna be so bad.
It is very easy! We all know that the American banking system is a virtual bubble based on empty zeros in the banking system. It would be enough, if about 10% -15% (maybe even only 5%) of people asked for the withdraw of deposits and banks become insolvent. Hasta la vista

That will be true when people have a lot of money in the bank, but what I know the rich control 99% of the money supply, the withdrawal of 1% money supply from the bank would have likely have no impact on the bank run that happened on the last decades. When the few very rich at the top control all the money supply, the rest of the plebs can't do shit to ruin the bank.
