At the bottom of the BTC daily line, no matter whether you can go long or not, you absolutely cannot go short. The only thing you need to do now is to wait for it to fall a few thousand points, so that you can comfortably buy the bottom. If BTC does not fall, you have to look at the subsequent form. For example, in the past, once BTC clearly reversed its trend, the general increase was more than 5,000 points. Now the increase is too small, not unilateral enough, so you can't go long, unless you insert a deep pin below 56,000 and then quickly withdraw it, which can be a signal to go long. If there is no pin, turn your attention to the altcoins that rose in advance, and continue to go short on the altcoins!
