hello ,,
i just want to invest my BTC with a good Altcoin for longterm investment,, with proof of stake system

so i can staking my coin too
maybe 1 - 2 years from now,,
I feared that such a long term is to risky for alt coins to invest in, the only thing I know is that for a less risky investment, why don't you just stay on BTC. If you really wanted to invest in alts, choose the top which I think is the ethereum.
