The only one I really trust is bitcoin honestly. It's been battle tested for a decade. Ethereum is cool and all, but there is a lot of room for exploits, and its still pretty new out there, who knows what could go wrong in the next year.
I'm just looking forward to the value of ethereum in the future, other than that I also admire to the good movement of waves in the market seems that it will continue. In terms of coins of course the most trusted for me is the bitcoin because this coin will have a lot of potential to handle any problems, also they can adopt easily the situation of crypto currency.
