At 8 o'clock on April 13, Beijing time, the ChaiNext 100 index, which reflects the overall trend of the cryptocurrency market, reported 626.50 points, a decrease of 0.81% in the past 24 hours, and a turnover of 72.939 billion U.S. dollars. The transaction increased by 9.62% from the previous 24 hours. 66 of them rose and 34 fell; the ChaiNext 5 index, which reflects the performance of the blue-chip cryptocurrency market, reported 543.50 points, a decrease of 0.89% in the past 24 hours, with a turnover of 59.247 billion US dollars, a 11.31% increase from the previous 24 hours; the Bitcoin Bubble Index ( BBI index) reported 77.10 points, up 0.44% in the past 24 hours; USDT OTC Index (USDT OTC Index) reported 103.54 points, up 0.23% in the past 24 hours. At 6 o'clock in the morning, BTC changed from rising to falling. Without obvious bearish conditions, it retreated from 7180 US dollars to around 6580 US dollars, breaking multiple support levels such as 7000 and 6800. The top 20 mainstream currencies have not seen a strong trend, mainly following the decline. It is worth noting that USDT currently has a premium of 3.5%. Even when the market rose yesterday, it still maintained a premium of 3%, which is a relatively abnormal phenomenon. And the rhythm of the USDT's slow rise is not like buying from the bottom-up funds, but like the big funds are slowly attracting goods, and follow-up needs to be maintained.
