The higher the risk the better the return. This is basically the reason why some investors will look for low marketcap coins with a nice team of developers. But take note that such projects are very risky. The moment their star developers leave the team, the entire project will be shattered. It is better to go for higher marketcap coins but with solid names. Even if their star developer is gone, they can still move forward, taking a new developer, and still create an impact to the crypto community.
