At 8 o’clock on March 22, Beijing time, the ChaiNext 100 index, which reflects the overall trend of the cryptocurrency market, was reported at 555.55 points, up 0.35% in the past 24 hours, and the turnover was US $ 78.969 billion. The transaction was 30.60% lower than the previous 24 hours. 48 of them rose, 52 fell; the ChaiNext 5 index reflecting the performance of blue chip cryptocurrencies at 483.04 points, an increase of 0.14% over the past 24 hours, and a turnover of US $ 64.381 billion, a decrease of 31.25% from the previous 24 hours; the Bitcoin Bubble Index ( BBI index) was reported at 71.69 points, up 0.45% over the past 24 hours; the USDT OTC Index (USDT OTC Index) was reported at 103.21 points, up 0.39% over the past 24 hours. The five-day line of BTC and the major mainstreams turned upwards. It pulled back deeply yesterday and also stepped back on the plunge of the last large Yin line entity and obtained effective support. Based on past experience, short-term intervention can indeed be made. It is a pity that BTC currently does not take an independent market and is subject to a lot of restrictions. It still needs to refer to the US stock index futures trend that opened on Monday morning.
