In my opinion, it is almost impossible to predict which cryptos will perform better in the coming years, taking into account that more and more new coins are emerging every day and it is likely that new cryptos with better advantages will emerge during this time. Meanwhile, I'll stick with the classics: bitcoin, ether, Ripple, Litecoin and maybe waves, steem and deeponion.
Best
Coin to keep in 3 years? I do not think it's that much. Is not that a very big number, I think with the
Coin on the market today, that's impossible.
Let's talk about stability and price. No
Coin is the same as
Bitcoin, all
AltCoin tend to differ greatly and lag with
Bitcoin developments. So if we expect in 3 years the price of an
AltCoin will rise dramatically just like
Bitcoin, I think the odds are very small. If we invest into
Bitcoin and wait for 3 years, I make sure it will produce
enormous results.
So if told to say 50
Coins, I do not think I can. Maybe I can only mention a few
Coins only:
BitCoin,
LiteCoin,
Ethereum,
Zcash,
Dash,
Monero, etc.
