In the volatile world of cryptocurrency, perpetual futures are a go-to for many traders. These contracts don't expire, relying instead on a mechanism called the funding rate to balance market forces. Recently, Bitcoin's perpetual futures saw a dramatic shift. Typically steadied by consistent positive funding rates, a sudden plunge into negative territory coincided with geopolitical turmoil and a significant drop in Bitcoin's price. This shift in funding rates not only shows a rare bearish sentiment but leads us to wonder, what does this mean for the future of Bitcoin trading dynamics? Could this signal a more profound change in market sentiment?
