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 will not be meaningless if you choose the top altcoins in this market. In the past 2 years, all altcoins have collapsed and a lot of altcoins have died, if you hold altcoins outside the top 100 coinmarketcap, you will never get profit from it, those altcoins do not have any empty and just created to scam investors
