The eternal profit master of the stock market: On the day before the market opens, he predicts the rise and fall of all stocks in his WeChat Moments and sets it to be visible only to himself. Then, the next day, whichever prediction is correct, he makes that post visible to everyone, while the post's timestamp still shows the previous day. Thus, you will find that this teacher always seems to magically predict correctly one day in advance. The eternal profit master of the crypto world: Every so often, he opens a long or short position with just 1U, and when the profit ratio rises, he pulls out that position and asks his family if they followed along this time and enjoyed the profits. This "Eternal Profit Master Teaching Manual" is worth 100U. Those who see it please make a payment voluntarily.
