According to Liquidity Doctor on Twitter, Bitcoin's main trading levels are positioned at 91.5k, marking the previous range low, and 88.8k, which serves as a critical support/resistance level. If Bitcoin loses the 88.8k support, it could potentially drop below 80k. Furthermore, the untapped high timeframe liquidity zone between 71k-71.5k is identified as a major reversal level for a potential swing bounce, offering insights for traders to plan their strategies.
