BitMEX's Chief Growth Officer Raphael Polansky recently highlighted a potential concern for Bitcoin (BTC). According to Polansky, data from the U.S. Treasury's Reverse Repurchase Agreement (RRP) facility suggests signs of liquidity tightening. Historically, an elevated RRP has tended to indicate a negative correlation with Bitcoin's price. This observation raises concerns that the current liquidity situation could potentially hamper the cryptocurrency's growth. As such, it is crucial for market participants to monitor the RRP's developments closely to gauge their potential impact on BTC.
