I just want to share my sincere thoughts... Does the price of something drop by 30% one day and increase by 20% the next? Doesn't anyone say what's going on??? No matter what, does the price of something change by 50% in a day? What happened, did war break out, famine broke out, what happened? Is such a market acceptable? Just think, I go to the market and one day it's 5 and the next day it's 25 or vice versa, what do you think? Are you kidding me? Don't you say?
