When BTC is 60000 yuan, I think 30000 yuan is worth buying, but when it really reaches 30000 yuan, then: Some people think it will continue to fall and don't buy. Some people think it's similar and just buy it and set it up. But the difficulty of the former is that even if it falls to 16000 yuan in the end, I won't buy it yet, and if it rises back to 230000 yuan, I won't buy it. In the end, I may buy it for 40000 yuan. The latter is covered when bought, and then wants to be cut. The only victory is not cutting even if you put it on, you can still buy it if you put it on, it has always been like this.
