The short-term support of Bitcoin is 67,000-68,000 US dollars, and the short-term pressure is 59,800-60,800 US dollars. The three major US stock indexes rose across the board. Grayscale is still the largest seller of Bitcoin and Ethereum. Yesterday, GBTC had a net outflow of 72.9 million US dollars and ETHE had a net outflow of 27.7 million US dollars. As I said yesterday, Bitcoin has heavy selling pressure and needs a second bottoming out technically, so Bitcoin will be mainly volatile in the short term. From the K-line pattern, there are many upper and lower needles, indicating that the long and short sides are fighting fiercely. There is no mid- and long-term layout for the time being, and the short-term high selling and low buying are the main ones. Leng Feng is concerned about two points. One is the upper key point of 63,000 US dollars. If it cannot stand, there will be no trend of rising. The other is the lower key point of 53,000 US dollars. If it does not fall below, there will be no risk of a new low.
