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.
That happens with 99% of the alts and 100% of the shitcoins, I learned it in the bad way as well, If you want something for long, go BTC, and ALTs for short, always be ready to dump them.
