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.
It will be difficult to replace Bitcoin with any other coin, because of the consciousness of people who always see the maximum goal of trading or investing in Bitcoin or withdrawing from Bitcoin to Fiat.
