I still recognized wanchain, ICON, Nash exchanges, if you are still holding then this might be a good time to sell them for good money, I'm talking about this altcoin season though, I believe that very soon all altcoins will surge higher, though I don't know if all these altcoins are still active or not but if development is still ongoing then it's a good thing
Every bubble has to have its paradigm. 2017 bitcoin bubble paradigm was - new global money that will replace fiats. After bitcoin hit 20k, network was so spammed that transaction cost 200$ (paradigm failed). Than every investor start to search for "new bitcoin", faster, better that could replace bitcoin as new world currency. Market was also full of retail investors with very low experience in trading/investing. That's why money flooded into altcoins creating alt season with 100% daily gains.
Will such thing repeat? I strongly daubt. If we will see next bitcoin/crypto bubble it will be institutions/professional investors/professional traders money with paradigm - 5% of every well balanced portfolio. They will not invest in link - oracle ... worth $ 5 bln without any documented profit, they will not invest in promise of something worth $500 mln, they are too smart to do that . What I'm trying to say ... most likely, during this crypto bubble, we will not see good gains on alts. Current ALT/BTC price might not repeat ... ever.
I would start to dump them all. Slowly ... not everything in one day, not everythign today. Just try to find tops and dump few% of investment. Find another top and dump again. Try to get rid of them but slowly. Maybe some of them will pump but it will be pump and dump, use pump and dumps like smart money, to dump.
