Note that just now BTC2 failed to break through 69,000 for the first time, and the large-volume pin went directly to 70,000. Here we need to prevent the risk of a correction.
66800 is the current key support. If it falls below, it will easily weaken, followed by 65500. If it falls below again, it will easily go to around 62000.
Therefore, you can consider short-term or spot position hedging here, and stop loss tonight at the pin point contract price of 70350.
Can be considered operationally
1. Wait for a weak rebound near 0.618 (half of the normal position is short near 68600), and increase the position to the normal position if it falls below 65500.
2. If the level falls below 66800, the normal position will be short by half, if the level falls below 65500, the position will be increased to the normal position.
