Who says small positions can't steadily make money? I started with 117 RMB and took 20 days. The margin usage ratio did not exceed 10%, and I successfully achieved close to 4000 in profits. Steady profits were realized through AFI quantitative methods. The software and strategies were also self-developed. Now starting to take orders. May all the cold scholars under heaven rejoice, and may they remain as stable as a mountain in wind and rain. $BTC $ETH
