I will suggest Ripple, Monero or IOTA. But as the guy above said you could try with some of the new upcoming ico's like eMarketChain or just invest some time to check what is coming on pre-sale and main-sale. I prefer to invest in new ICO's with a very low starting price: under 0,1$. Normally after the main sale, they have at least 100% profit. Will check now eMarketChain and will try to calculate the starting price. Will reply again with the result of my research.
As far as I see eMarketChain are going to sell their token for 1 ETH =11,500 EMAC. Isn't that too low?
They have some bonuses during the pre-sale and main sale but looks like the average would be 0.04$, which is actually what I am looking for (under 0,1$). Hope to bring a lot of investors during the pre-sale and main sale, because with this price, it would be completely possible to gain 100+% profit in a short period of time.
Don't have spare time now to read more about them, but will try to do it later.
P.S
And please do not consider my opinion as too relevant
