Look for something with max supply of only like 1 million. (which of course needs to have a utility too to stay in growing demand)
We seldom see projects with that supply the lowest I've seen was 5 million but the supply is not a guaranty in the success of the project Tron and Ethereum have billions of supply but look at their standing in the market they are doing great and fine, Ethereum is in the second spot, it's not the supply that will guaranty success there are many factors and platform and usage are just two of the main factors, marketing plays a crucial factor too.
