In my opinion, before investing in any altcoin I consider the activities of the team, the use cases of such projects and find out if they are following their road maps. When all these are in place I go ahead to invest. For instance I invested in #Bluzelle recently after following their activities, I noticed their mainnet was launched and staking began  when they promised to and the price of #Blz is growing organically not pump and dump. These are some good signs of a good project.
