Yeah thats true, but I think this is another problem how to convince people to change from fiat to crypto. But in this post I am more interested how well it would work if this step is already done and ALL people use only crypto as a currency. By thinking that way it makes it easier to find problems with crypto as a world currency and maybe tackle those problems.
I think this is important to discuss so that we have good arguments in convincing people to use crypto currencies.
I think there is not plenty of problems with crypto currencies it is pretty straight forward, I think it will not be to about the point of convincing people to use them or not but who wants to own them and how much exposure will they give to people. Most of the things we use now have been imposed on us so cryptos can as well. What if a big bank gets a hold of half of all the bitcoin and imposes it al lover the world. price will increase for him and people will use it. problems will arise but as long as it is supported by ppl up there all that will mean absolutely nothing. banks are a HUGE scam and people still uses them...
