Crypto is at its infancy, nobody knows which one is going to be the one that emerges like the heir of fiat. There might be a third one that has not yet been released yet that could overthrow bitcoin, litecoin and the other alts alltogether. Bitcoin is strong and litecoin a good second, so it is a safe bet for those two at the moment. Bitcoin has the biggest supporting crowd, the largest adoptation and albeit the FUD spreaders there are more places where I can buy with bitcoin than I can with any other coin.

I do spread my chances, got some litecoin as well, so either way I am confident the future will look bright, so bright we will need to wear sunglasses every day
