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.
You held in the wrong time, in 2017 and 2018 crypto market was in huge bull season and that's the perfect time to sell coins not hold them, it's you that failed to understand how crypto market works and now I think another opportunity is around the corner, that is if you are still holding the altcoins, even those who invested on bitcoin @19k in 2017 are now in profit so anything can still happen
