I think best idea are low difficult ICO's or whatever, i get 12 MH/s actually doing Musicoin is that a good idea?
Try mining coins that are not so popular as of now and mine a ton of them. This will act as a learning curve and do go for coins that you believe can become high in value in future.
Check announcements page for such. A few examples that I can give are Trezarcoin, Denarius, Votecoin.
