I can not give you financial advice, however if you check upcoming events for:
OYSTER PEARL: main-net, and SHL airdrop are coming. I would expect a significant rise before the release and a 20-30% drop afterwards. The price of SHL remains a surprise. But since the airdrop it is 1:1 ratio it could be that SHL will be the same price with PRL.
TRAC, main-net is planned too, and the project looks having great potential due to adaption, therefore a 10-20x is not impossible.
I hold both. For the other coins can't say much...But if you scroll on their forum pages you could be able to learn more.
Good luck
