Lets see. 10 Eth you'Ve got. Suggest you split them and invest in alts, no one can tell you which one will jump for sure.

Good research from your side needed. Dont invest into one certain coin, this strategy is risky.

I can advise you to check out CAT(Bitclave). Price is still low; project is good as I see it.

Bitcoin is the safest investment but can take some time to get real profit. I believe Bitcoin will go real up in 2019, now it is resesion time.

But for sure all you are the one to deside what to do. Good luck
