The most important currencies in the world are the USD, EUR, YEN, GBP, Swiss Franc and a bunch of other dollars mostly, the yen too.
But why would we need hundreds of cryptos, even thousands? Do you think this will be how the future looks like, or do you think after some more bear markets and crashes there will only be a few big ones left? Like now there are so many coins lets say between rank 10 and 200 that honestly, nobody needs, or? Do they even have a future? Or do you think it will come down to be sth like this:
Fiat world got its USD, EUR, YEN, GBP, Swiss Franc, YEN
Crypto world got its BTC, ETC, XRP, ADA, DOT (?), probably two or three more new players that will emerge after the next crash – and then the rest is wayyy behing, and not even close in market cap.
