Wait and see what happens on a bank run. Oh not you don't, just look at history like 2008 in Greece.
Yeah and it has nothing to do that there are only so many people willing to pay 2x (eg supply and demand), that the pandemic is over and people go out more again and game less and that both main vendors plus a new 3rd one will release there products in the next couple months.
What people said was that crypto isn't the only reason and likley not the biggest one.
How about a currency that is backed by the people and controlled by the people? I know, it takes some vision and foresight to see past the current system. Saying it is backed by a goverment can be interpreted in different ways. Like it is also controlled by the goverment and by proxy the rich and powerful behind the scenes and used for their advantage alone to stay in power. And when it doesn't suit them anymore like the upcoming (next decade) hyperinflation, it will get dropped like a hot-potato.
I good thing about crypto is that it makes you read upon how the current system actually "works". That is actually my bigger gripe. In very simple terms: We are all being exploited. For every 100 Mio loan the rich take, your saved dollars are worth a little less. And with that 100 million they buy hard assets like real estate which will keep value even when the dollar implodes.
