Contract players, I recommend that you operate in the most stable way. Whether it is the U-standard or the coin standard, it is recommended that you consistently only use a fixed principal to make a single, such as a total of 10w on the platform, then you usually only use 1-2w u to find an opportunity to do it, don't open a single today 2wu to earn 2w .u, tomorrow to make a 4w u order, tomorrow to earn 4wu, the day after tomorrow to open a single of 8w u. There is a fatal flaw in such a similar doubling game, that is, in the end, if you hang up, it is likely to be zero. Don't learn from Mr. Bao's set, and don't leave yourself a way out. If you want to learn from your uncle, take precautions, have a sense of crisis, and leave yourself a way back.
