BTC has once again tested the support of 80500 below and is now rebounding. The buy orders below 80000 are still quite strong, and the market is currently fluctuating within a very small range. The current situation is that there are buying orders in Asia, but as soon as the US stock market opens, there will be significant selling orders. Short term profit taking and the decline in the US stock market have caused most investors to be unwilling to stay in the market too much, and they will first put the profits into their pockets After a night of turmoil, the market has returned to the starting point of yesterday's rise. Personally, I believe that the 80500 level should be able to support itself well this week. There is no impact from the US stock market on Saturday and Sunday, and the market will rebound. This wave is around 86900.
