Analyst Xiao Ma's Diary: 2/15 Bitcoin and Ethereum gradually rallied and oscillated back and forth last night. Last night, I planned to short around 70,500 and 2,100. The market oscillated downward, and it directly dropped to around 69,212 and 2,034, where I exited in time. The Bitcoin and Ethereum short ideas yielded nearly 1,300 points and 70 points of profit, successfully capturing the move. As long as you grasp the trend and swing trading, in such market conditions, with good entry points, both long and short positions can yield significant points. Although the journey was somewhat winding, the market control remained rigorous, and the final outcome was still positive. I believe that recently, participating based on Xiao Ma's strategy has been highly beneficial. Always focus on real-time tracking and guidance, and keep up with the rhythm. Tonight, you can continue to go long to push the price higher, then short Bitcoin around 70,500-71,000 with a target near 69,000; Ethereum can be shorted around 2,080-2,100 with a target near 2,000.
