I hope bitcoin is the better crypto currency
Compare to other altcoins, it's not just a better cryptocurrency but it is the best of them all. But everyone has their own preferred coin base on speed and cost.
Based on speed and transaction fee there maybe other coins is better than bitcoin but when it comes to acceptance level bitcoin is more preferred coin in all the gambling sites and most of the people can convert their winnings into fiat if they are in bitcoins.So yeah bitcoin is best.
