Iam the same situation because i dont cut loss when big down happen. But i dont have choice, I just hold it for long term investment. Im lose in some potential coin like WAVES, ETH, DASH because bought on the top. I believe by hold it in a years will give some profit.
I had the same with the Waves, not so much money, but bought also on top. But i´m optimistic that in on year, the waves are much higher than they are actually. They did just start.
