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.
This is your fault, something I've done in the past myself, seeing profits and refused to take them thinking the price will keep surging, in crypto space surging don't last forever, always take profit while there are pumps
