Let's do a review of BTC, it's been a typical day today. Last night's stock market crash drove BTC to fall below 85, with a downward clearing pin of 837, Then it rebounded and fluctuated, and at 4:30, it began to rise, testing the resistance of 87. It can be seen that there is buying in this process, with spot contracts driving, but there is no growth in OI. This stage mainly involves closing short positions and buying spot contracts. 8: It's quite strong that the 00 Asian handicap hasn't fallen below 86, and I had hoped that it wouldn't even reach 855. Then the Asian market kept testing 87 until it broke through, and then it held at 87. 16: At the opening of the 00 Euro trading session, we first tested 86 downwards and did not fall below it. This indicates that there is no problem with the foundation of 86 and it can continue to rise. At that time, we also mentioned in the group chat that this was our entry point. At 21:00, the US market opened with a retracement of 87, which was confirmed to be stable, and then began to push up.
