I think bitcoin is your "safest" bet, ethereum forked before...
If Ethereum has forked and is past that hurdle that has unknown consequences, and Bitcoin hasn't...how does this make Bitcoin a better investment?
Maybe you should research for yourself so that you could see the result and you must be wise aswell as be more observant since there are several downfalls happening on it. And you must join each downfall happen so that you can earn with the pumps happening.
But you shouldn't be calm that there's always profit on bitcoins since particularly many people lose their capitals for not being attaintive to there investment on bitcoins.
