# **#BTC交易 # Trading Story**
On May 9th, when BTC broke through $103,000, I went long, based on a net inflow of $4 billion into spot ETFs in one week + CME futures premium surged to 1.8%. Set a dynamic stop-loss at ($101,500), and after holding for 16 hours, I took profit at $104,200, gaining 3.1%. **Lesson**: In an institution-led market, it is essential to closely monitor ETF fund flows and derivatives data.
