How did you "know"?
Well, I mean of course I didn't "know" but I felt it very strongly. I work with servers so I am surrounded by monitors at work and home. I watch these markets a lot. I felt I had a good grasp on what was happening when I was in the middle of it. Then I made decisions contrary to my instinct and watched what I could have had evaporate.
The zen of shitcoin trading I guess.
