I am really on the face regarding bitcoin though: it is the grandfather of all those crypto projects and massively moves the market, but I don't quite understand how it could ever replace a currency given its very limited supply and astronomical unit economic price: it was not supposed to be a store of value like gold when it started.
Ultimately, I think a few projects with much higher coins in circulation and faster transaction times will end up becoming more valuable due to greater usability.
It's a shame it feels like REQ is a bit late to the game, but they do have ambitious plans, one of them is to enable cross-currency transactions (including fiat). No-one has yet gained the first mover advantage in this space so the jury is still out.
