It's best to sell any altcoin that is worth less now because most of them might not survive this bearish market so it would be a lot to foolishly hold on to coin that doesn't have any future
I agree and I have done it before you say this. Initially I was very confident to hold KICK and CRPT until next year, but after running for 3 months the value continue to dropped, so I decide to immediately sell it. If I still hold them until this day I can't imagine how much loss I will get. So from this incident can be concluded that holding altcoin especially tokens for a long time is not recommended, because the value tends to decrease.
