Some characteristics of the bottom: 1. Falling below the cost price of mainstream K machines, K machines surrender and sell. (The cost price is about 16k, and it has fallen below once last year. The second half of this year may be the last chance.) 2. The cost basis of short-term holders is lower than that of long-term holders (the long-term here is 1-2 years) 3. Black swan events, the kind of bad news that is enough to make your faith collapse, such as (the successful advent of quantum computers, the explosion of a certain exchange). In short, the bookmakers have enough bad news to make you dare not get on the bus, or there are discussions that follow what others say. 4. Emotional and non-technical signals. For example, when I post on Weibo, no one reads or likes it.
