Bitcoin's support between $88,000 and $90,000 has weakened significantly as Gamma exposure declines, according to on-chain data analyst Murphy. The Long Gamma at $88,000 has shifted to Short Gamma, while the $90,000 level maintains Long Gamma but with reduced options Gamma exposure (GEX), dropping from $1.2 billion to $590 million. This change suggests diminished support in this price range. Despite this, the GEX at $92,000 has increased to $1.4 billion, potentially increasing BTC's volatility. The token structure remains largely unchanged, with significant concentrations between $87,000 and $92,000, indicating strong support. However, if this range is breached, BTC could move downward to fill the gap below, with the midpoint of the dual-anchor structure around $72,000 to $74,000.
