The argument for bitcoin always has and always will be that it is mankind's one single shot at trying to separate money from state. The challenge is that money itself, the very concept of it, is a network good, meaning that it lives & dies by the network effect. The more people that trade their dollars or altcoins or any other tokens in for bitcoin, the stronger it becomes, and the more successful we are at separating money from state. Humanity is only going to get exactly 1 chance at doing that. Governments will see us coming miles away next time. They already see us, but bitcoin is too large for them to stop. Not so with any other coin. So if Bitcoin fails, for any reason, you can expect CDBCs to be the new definition of money for tens of thousands of years.
