On a technical level, Bitcoin is worse than a currency because it’s value can fluctuate wildly constantly and transaction fees are high. I don’t know what’s going to happen when we get a “Run on the bank” type of scenario but I suspect it’s not going to be good for the little guy.
The ability of central banks to manage a crisis isn’t a bug, it’s a feature. The trade off is one we’ve made throughout history, we have to give control to other folks who may not have our best interest at heart.
I fundamentally believe Bitcoin will collapse the next time we have a global economic catastrophe and it’ll have no tools to handle it.
