Well as someone say is not the best way to invest on Bitcoin hex or any other coin named Bitcoin x, y... and coin named, because they say that this coin are just some copies and over time may fail and just lose money.
The funny thing about projects like these is that , this developers have mission, to give you useless coins to you and collect you Bitcoin. Funny isn;t it, where are Bitcoin, SV, Bitcoin Gold and co now. I am not saying ALtcoins are useless but most will end up valueless and worthless with time and you don;t want to be bagholding them
