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.
As your experience if you sell your coin now, you will be disappoint again. Take your steps as cryptocurrency market situations. Unfortunately that time ii lost huge money for holding tokens and coins. Always fixed the selling price before you buy any coins. To buy a coins, price dump should be needed.
