Bitcoin is the most famous cryptocurrency but it has a lot of bad rep. Which altcoin do you think can take the crown from bitcoin in the future and why do you think it would be? I see cryptocurrencies lasting for a very long time with the possibility of being a true currency if not in this century then the next so I think it's just a legit curiosity.
in term of technology, bitcoincash is the most similar to bitcoin.
in term of funtion, every coin born to replace bitcoin, that's why they're called alt-coin.
but I don't think there would be any coin could replace bitcoin, atleast for near future.
