I just released almost all the tst. I bought about 8 million pieces in total, and when I doubled, I sold 4 million pieces. There are still over 4 million pieces left, and almost all of them were sold at an average price of around 0.35. The total profit should be around 150wu. I don't know how to conduct a review, as luck does play a major role in making money. Anyway, Nai Zi Ge has fulfilled his promise and always kept it.
