you have a grand to spend and then you're off to a desert island with no contact from the outside world for five years.
which coins will still be alive by then and which will be thriving? as i'm on the conservative end of things i'd only go for bitcoin myself. in half a decade an insane amount will have changed.
what about you?
My pick Eos, Stellar, ONT, NEM, NEO. If I invest for 5 years, I will not risk and look for not popular coins, because in 5 years the market can change very much. But I think that these coins will remain, because they have good teams, a good product and I think a good future. But in fact, if I invested for such a long period, I would choose only Bitcoin, because only in it I'm sure.
