Binance's largest order-carrying trader, Tortoise and Hare 985, can almost be considered liquidated today, with a seven-day retracement of more than 95%. Not long ago, I saw that the largest user who followed his order had a principal plus profit of more than 40wu, but today it is only 7wu, and the principal has also lost more than 10wu. Tortoise and Hare actually do both left-side and right-side trading, but based on his winning rate, it can be judged that he mainly trades on the left side, and almost all of his orders are huge losses. Left-side trading is suitable for use when the market fluctuates up and down, and it is necessary to strictly control the position. Once the position and leverage are too large, and there is no stop loss, sooner or later it will encounter a one-sided market and finally be liquidated. Let's talk about a big guy I saw recently on Station B. He went from A6 to A8 in less than two years. He follows trend trading, which I understand to be similar to right-side trading. This kind of trading has a very low winning rate and often requires stop loss. Once the trend is successfully grasped, you can roll the position, which will bring considerable returns. Loss aversion makes people very reluctant to stop loss when trading. Learning to stop loss can be regarded as a major threshold for becoming a trader. By the way, the boss recommends that the easiest way for ordinary people to invest is to invest in Nasdaq 100 (I agree with it)
