Smart hodlers bought several coins during the crash (
"buy the freaking dip!!" is a way of life to hodlers), the rest either panicked or decided to stay away from the internet because they couldn't handle watching their portfolio bleed out.
Much likely they are in regret right now. Especially the price slowly recovering.
I remember reading the WO thread a few weeks ago when we flash crashed to sub 5k, there was this user there (I believe a long time hodler, can't remember the username) who panicked and sold most of his coins...Obviously, he regretted it the next day 'cause the price went back up again...Devastating.
