Late 2017 and early 2018 i was holding lots of coins and tokens from the ico's in that some i really trusted with solution and team (not only me most of crypto community trusted). Now this coins or token became nothing . But some projects i entered to sell for small margin profit these projects given profit . So holding token or coin for long term is meaningless.
It means you aren't good at picking the best projects, every coins and tokens have use cases the difference is some are better than others and some are not even needed at all, you need to work on how you do research on projects and the best coins to hold are popular altcoins, if you are going to new coins go in with limited fund
