According to CoinDesk, cryptocurrency research firm K33 Research stated in a market report released on Tuesday that although investors are still concerned about the risk of further decline, there is a reliable indicator that suggests a significant rebound in the market in the coming weeks and months.

According to the report, the 30 day average funding rate for Bitcoin (BTC) perpetual contracts has dropped to negative levels, a situation that has only occurred six times since 2018. K33 analysts Vetle Lunde and David Zimmerman wrote:

In the past, when monthly funding rates hit negative levels, it coincided with the market bottoming out

The report points out that based on the previous situation where the indicator flipped to a negative value, Bitcoin's average return rate in the following 90 days was 79%, and the median return rate in 90 days was 55%.

Meanwhile, due to the influx of short positions, the open interest in derivative contracts gradually climbed to the highest level since late July. The report points out that, combined with sustained negative funding rates, these indicators indicate potential short selling risks in the market. The analyst wrote:

The similar funding rate environment provides very strong reasons for active exposure to BTC in the coming months
