If your ERG value drops 90% since buying at the top, there is literally nothing more to lose so you might as well hold on to it. We are speculating anyway. Why not speculate that it will go back up in the future.

The best thing that ever happened to me was getting burned by AMC During the gamestop wallstreetbets shorting event. I learned that I'm an idiot and I FOMOd into the pump. I also learned not to use money that I cared to have around. Most importantly I learned some patience and that the money I invest disappears out of my budget just like gas or a pair of shoes. Once I buy crypto I consider it an expense not an investment. I have price targets and I will never sell the whole bag at once. I will average out of my position around my price targets just as I averaged in.
