I would pick Bitcoin. It is the most decentralized, it has the best engineers dealing with it, and it's appropriation is developing for a long time... There are even a few nations where individuals are having the capacity to purchase merchandise and enterprises utilizing just Bitcoin. I figure there isn't yet an altcoin that gives you that sort of advantage.

The value of the bitcoin are best among all altcoins and that's the reason why I choose bitcoin and invest on it for the sake of my money and I know bitcoin can gives me better life in the future.
