If and when cryptocurrency finally becomes an official global currency, how do you think it will affect the global economy and the economy of each countries? Will it help improve the economy better than fiat or will it still need help from fiat?
First what makes you think that it will be the globe currency at all? I mean the debate is still on that whether we should call the bitcoin as currency or just the asset that we can use for the purpose of store value? I mean with that ambiguous nature of bitcoin how can we expect it to see as global currency at all.
Also if it becomes the one then also it wont help the global economy to move vastly but on smaller scale because its use still would be not very much explored and hence could be more or less to a MNC companies equivalents.
