Bitcoin Derivatives Are The Earliest Signal Of A Quantum Selloff: Joshua Lim

Lim suggested that even an attempt at the first path could lead to the second. “Our only prophylactic is to EITHER A) burn Satoshi’s coins via governance,” he wrote, before outlining the trade-off, “OR B) create a hard fork and allow for the market to decide which is the true BTC.” In his view, that likely becomes a political contest over Bitcoin’s identity as much as a security response. He added that the most likely quantum thief, if such a scenario emerged, would be “a state-level actor.”

From there, Lim shifted from theory to market structure. He contrasted any future fork with Bitcoin’s August 2017 split, which produced BTC and BCH. Back then, he noted, Bitcoin was a roughly $45 billion, mostly retail market, and many holders welcomed the fork because it effectively created an additional asset. Today’s market is different: around $1.5 trillion, far more institutional, and wrapped in ETFs, listed futures, and options. That changes how risk would likely transmit.

“A hard fork today, or even the prospect of one, would be an entirely different beast,” Lim wrote. “It would result in extreme volatility and likely downward price action: a large gap down and massive cascading liquidations.” He added that if the community were close to evenly split on whether to burn exposed coins, institutional investors might have a mandate to de-risk ahead of the event, amplifying downside pressure.

That is where derivatives come in. Lim argued the earliest warning signs of q-day risk are most likely to emerge in long-dated options skew, forward basis, and the distribution of open interest across traditional and crypto-native venues. He pointed out that long-dated BTC put skew is near multi-year highs, with downside protection relatively expensive compared with calls, and said the last comparable elevation came around the Three Arrows Capital and FTX collapses in 2022.

He also flagged long-dated basis, noting that Bitcoin futures are trading near multi-year lows relative to spot. In Lim’s framework, q-day risk should compress or even invert basis because market participants hedge for downside while others position for a possible fork-related “airdrop,” similar in concept to 2017. Since the timing of any quantum breakthrough would be uncertain, he expects those signals to appear farther out on the curve.

Still, he stopped short of saying the market is already pricing an imminent quantum event. Some signals are “flashing red,” he wrote, but they can also be explained by broader systemic risks or secular shifts, including growing institutional participation through venues such as CME and IBIT options. For now, Lim described the picture as mixed. His broader point was simpler: if q-day ever begins to look real, traders likely will not first see it in dormant coins moving. They will see it in derivatives.

At press time, Bitcoin traded at $75,024.
