Last night $BTC still did not break through 115.8k, but the premium suddenly surged, indicating that the market may be attracting short sellers. Short sellers may short at this resistance level due to small stop losses, but I believe it is not advisable to short.

If the price briefly breaks through 115.8k and then falls back, and the premium drops significantly, then shorting would be cost-effective. If it breaks through 115.8k and the premium does not drop and does not break the top again, then you can go long.
