Look for small coins that you can buy a lot... Like Verge / reddcoin / digibye or maybe even ZNCOIN they are really cheap at the moment but if they go to like 0.25 cent you will have a lot of profit
I think verge is a pretty big one already. I call small coins the ones that have few millions USD market cap, those have also the great space for growth in case the team and the project are solid.
