For around the last year I have not seen one single coin that has been newly listed worth investing in most coins today are copies of others which have failed. There are no original ideas anymore and most are scams.
There are a lot, maybe you just not explore too much yet. I think there are a lot of new projects gaining success in exchange this year. Most specially NFT, there are a lot NFT based token which gaining more than 100% profit. New projects don't need a pure new idea, they could replace the old idea with a better one as long as it good, it will works
