There are some coins that have good potential in the future, including Bitcoin, Etherium and Neo. But in my opinion personally prefer Etherium to be invested because it has a fairly stable price for now, and I believe if Etherium has a profitable future.
for investment in the future why would you choose assets with stable prices? isn't it assets with stable prices there will be no increase in height. Anyway I think the price of the ethereum's not so stable. If you want a stable price of assets you can choose dogecoin, it's better. but I think the assets are not suitable for investment.
