What is your worst crypto investment to date?

I got caught up in one too many alts during the run up in the summer and I’ve been left with some that would need to treble to get close to their ATH. I cut a few at the beginning of the year to buy some BTC, which turned out to be a decent idea considering how much more most alts have bled in comparison, but realistically cash and gradual buys would have been the better option. I didn’t anticipate a crash like this, maybe that was naive, but here we are.

So yeah, was just wondering what has been the worst for people here. Maybe we got caught up in the same projects.
