What are some of the alts that you feel can give high profits like 100x in a year, by the end of 2018.
Do Golem, Nem, DGB, Siacoin have that potential in them?
What will be your picks for a year long investment?
I think the safest option is to invest in ETH for such a term. And if you now buy coins, then in the future you will get more profit.
We can't predict that we can earn much higher profit in only one year ,because this market not controlled by anyone which they depended on the demand and supply.
