Sorry, from the altcoin list you mentioned above I don't know at all, but if you think it's worth keeping it then do it. I will only recommend you to invest in the top coins / altcoin in markets such as BTC, Eth, Eos, Bnb, and PPT. at least to minimize losses, given the market situation is weakening. so always update your portfolio, not with coins that are difficult to develop.
But do not invest all the money in these coins, even though they are top the chance that they will still fall is, but as now is a good time to buy for the midterm.
