4.10 rebound or V reversal? Last night, the US stock market surged sharply in the cryptocurrency circle. What needs to be considered here is whether it is a rebound or a V-shaped rebound, whether to chase long or wait longer 2. There is only one real "V" in the history of NASDAQ, that is, the COVID-19 Black Swan in 2020. In addition, there will be another exploration or another decline 3. This round of BTC peaked on January 20th, while the tariff war started on February 1st, which belongs to the correction stage and encountered negative factors, accelerating the strength of the correction. It is not a complete black swan event I think there will at least be opportunities for a second round of exploration or even a new round of decline
