Liang Qiu: Bitcoin/Ethereum long positions should pay attention to reasonable range control.

Following last night's long positions (entering at 3560-3580, target 3670) and short positions (entering at 3680, target 3580), all positions in Bitcoin/Ethereum were closed with profits. Today, during the daytime trading session, we repeatedly reminded traders to enter long positions near 3475 and 3500. After a day of sideways consolidation, the market rallied in the evening, with Ethereum currently around 3580, gaining another 100 points. Bitcoin performed well last night, and we almost exited today with a small profit. All previous strategy videos are available; congratulations to those who followed our analysis.
