I myself have made similar mistakes of FOMO and it just seems like everyone does, like it is an oath to becoming a good trader. So you have made the cardinal mistake of FOMOing (dw we all have) now you are in a spot of hodl or sell I would hodl myself because I don't like selling at losses. Also you have to look at whether those coins or not have a chance of getting out of the red and as far as I know those are okay coins and you should be able to creep out of losses. Lastly, know that I am still bag holding a couple of alts from last year some of which I have had for 10 months now (and don't know when I can get rid of but will wait it out).
