Yesterday someone asked me if following A Feng's address is worth it. This is my small account that I tested today; I've been following for over 7 hours and lost 184U. At first, I didn't set a high slippage for following, which led to dozens of coin purchases failing. I have to say, A Feng really puts in the effort, trading at least a few hundred times a day. Conclusion: I do not recommend following; A Feng's win rate is not high. His secret to making money lies in having a large capital and frequent trading. As long as he bets on a big one, he can make up for the previous losses.
