I am giving you an idea.
https://www.betterhash.net - this is a simple GUI that does benchmarking and mines the most profitable thing now by using charts.

But never trust anyone without doing your own research!
Minergate is another GUI option but many say it's a scam. I also say that because the fees you pay to them are 10 times what they should be.

I would say you would mine 150 hash/s ZEC ( Zcash)

Use this calculator:

Don't forget to add your own power costs to find the real cost.
Cheers and ask me if you have further trouble with it!
