During my earliest times in crypto, i made a couple of mistakes by selling valuable coins for cheap prices due to impatience. I learnt my lessons and came to terms with the principle of HODLing. The market has always been recovering throughout its history and this is what motivates me to hold.
I am, also holding most of the coins I used to but before. I made the exception for Ripple: I exchanged it for the other alts I trust more. Here, my choice is like that: ETH, NEO, EOS, Cardaro, TRON, Stellar and some other altcoins more.
My motive is simple - next rise I will have 10x or even 20x more money! Just keep patience!
