$WLD WLD has a pattern. I don't know if you have noticed it. It starts to fall in the early morning of Wednesday, and generally lasts until Thursday to Friday. There may be some trouble on the weekend, and sometimes it even starts to fall on Tuesday. Because Wednesday morning happens to be the day when the bankrupt Afro Exchange sells WLD on Binance.
I can't say it is particularly accurate, but at least it is more accurate than the period of the test girl sitting next to me. She had her period at the beginning of the month, but I saw that she hadn't changed the maternity towel in the drawer for several months. The pressure of work has overwhelmed the lovely test girl! Oh, I feel sorry for her.
