Trading is really against human nature. The long-short ratio of Bitcoin has been getting lower and lower in the past few days, and more and more people are shorting it, but Bitcoin continues to rise.
The theory that most people lose money has always existed. Bitcoin has risen in resonance in large and small cycles. The upper pressure is around 71,000. It is better to be cautious about shorting.
If you can't beat it, join it, brother.
