Let's analyze BTC briefly. BTC hovered before 70,000 for several days. It finally rushed up and fell back. This gave people an opportunity to short. BTC has three major resistances of 70,000, 71,800 and the previous high. That is to say, you can consider entering the short position when BTC breaks through 70k, adding positions at 71,800, and stop loss at the previous high.
At present, BTC is still in a bull market, but there are often several months of wash-out time before the bull market breaks through the new high. The most common thing in the bull market is that the price is still the same price, but the money is washed out. Therefore, it is necessary to operate with caution and wait rather than chase.
As long as BTC does not break through the new high, there is a short-term short-term opportunity in principle. Of course, there is a more stable choice, which is to open a BTC neutral grid with an interval of 20,000 points above and below!
