Warning about the increase in Open Interest (OI) on Sunday with a negative funding rate, creating a short Bitcoin attraction but avoiding crowded trading, waiting for volume to increase on Monday to determine market direction. The chart shows low weekend liquidity leading to traps for both long and short around the 65k-67k $BTC level, where there are many liquidations; the put/call OI ratio reached 0.84, the highest since 2021, reflecting a strong defensive position from investors. The latest data (23/3/2026) confirms the funding rate is near neutral (+0.002%), with total OI around 24 million USD, suggesting healthier spot buying than leverage, which could support a breakout if volume increases.
