Bitcoin and Ether are trading inside a zone where the routine hedging of options dealers works against the market rather than for it, a setup that could magnify price swings in either direction until the two largest cryptocurrencies reclaim key thresholds.
According to Greeks.Live, market makers' gamma exposure (GEX) is negative - or short - across most of the range where Bitcoin is currently changing hands. The same structure shows up in Ether's options market. The largest concentrations of exposure sit near the $68,000 and $70,000 levels for Bitcoin, making those prices particularly sensitive for dealer books.
Gamma exposure measures how the net gamma of dealers' positions shapes their hedging. When exposure is positive, dealers are typically long gamma and their adjustments lean against the prevailing move, smoothing prices. When it is negative, the mechanics flip: firms must sell coins or futures as prices fall and buy them as prices rise to return their books to neutral, adding fuel to whatever direction the market is already moving.
"Both Bitcoin and Ether have slipped into deep negative gamma territory," Adam, a macro researcher at the options platform Greeks.Live, told CoinDesk. "Deep negative GEX means dealers are net short options - largely driven by traders bidding up downside puts or chasing breakout calls. To stay hedged in a short-gamma regime, dealers must trade with the prevailing momentum, not against it."
Market makers are the firms that take the other side when traders buy or sell options. They are not trying to predict direction; they earn the spread between bid and ask and hedge away the directional risk that price moves create. Puts are bets on a decline, calls on a rally.
The Greeks.Live chart for Bitcoin illustrates the current setup. At 12:37 UTC on Saturday, with the coin near $67,191, the negative-gamma bars stretched from roughly $58,000 to $72,000, with the heaviest readings clustered around $68,000 and $70,000. There was no positive-gamma cushion below the spot price, meaning little in the hedging flow would soften a drop until the area around the June low of $57,700. Ether's chart shows the same picture, with price sitting inside the red zone.
The risk extends beyond the options market. Perpetual futures, which carry no expiry date, allow traders to take leveraged positions. A modest decline can snowball into a wave of forced liquidations as platforms close losing bets, adding fresh selling to existing pressure. The same mechanism works in reverse on the way up, when dealers buy into a rally and accelerate it.
The dynamic could reverse if prices climb above $73,000, where the chart shows Bitcoin's gamma turning positive. At that point dealers would hedge against the market, potentially dampening volatility rather than feeding it.
"Until BTC and ETH reclaim their respective 'gamma flip' levels - the price threshold where dealer positioning turns positive again - expect fragile order books, exaggerated intraday wicks, and momentum-driven price action," the researcher said.

Gamma exposure is not static. It shifts as prices move and as options contracts expire, so the balance of dealer positioning can change quickly. That means the current amplifier effect is a snapshot rather than a fixed condition, and a move through a single threshold can flip the hedging flow from destabilizing to stabilizing.
For derivatives traders, the practical consequence is a market where intraday ranges may widen and stop levels near the $68,000 and $70,000 clusters could be tested more easily. For the broader crypto market, the read-through is that price action over the coming sessions may say more about dealer mechanics than about fundamentals, with the $73,000 level on Bitcoin serving as the clearest signal that the regime has changed.
