It seems that many projects still think there can be growth opportunities thanks to relying on successful coins in the market. To me, it's a redundant product in the crypto space, why don't people spend time researching new and more interesting things instead of creating copy.
Its not a problem if the copy project try to give additional value on its project, because sometimes the community of the copied project didnt want any change of its project. Example, Ethereum is a copy (fork) from Ethereum Classic, or Bitcoin Cash which try to solve some Bitcoin problem. But i agree, some project just copycat the name and value of the copied project which make the project becoming an useless one.
