I still hold my altcoin and i plan to my all coin holding for longer time beacuse altcoin give a bright future alt coin low now so i plan buy the coins.
Which altcoin you are holding because holding in long term will be suitable for only potential coin if you holding some shitty cpims those prices will fall more and more in the coming days.So check the quality pf the project and the project team before holding it roo long.
