FalconX co-head of markets Joshua Lim says Bitcoin (BTC) derivatives, not on-chain flows, will likely broadcast the earliest distress around a quantum computing event.
FalconX Warning On Quantum Risk
Lim laid out his case in an X thread on Apr. 16, splitting the problem in two.
The first question is technical, namely how Bitcoin migrates away from elliptic curve cryptography. The second is political, and concerns what the network does with Satoshi Nakamoto's dormant coins.
Lim pointed to BIP 361 as a proposal that covers both post-quantum migration and Satoshi-era holdings.
He estimated Satoshi's stash at roughly 1.1 million BTC.
Other old or lost coins could push exposed supply near 1.7 million BTC, a figure he called a "$127bn question." Any fork today, Lim added, would hit a $1.5 trillion market wrapped in ETFs, futures and options, not the $45 billion retail asset of the 2017 BTC-BCH split.

Expert Views On Q-Day Timeline
Other analysts disagree sharply on urgency.
Nobel physicist John Martinis, who helped build Google's quantum computers, said that a cryptographically relevant machine is roughly five to ten years out.
Bernstein wrote in an April note that the threat is credible but manageable, giving the industry three to five years to adopt post-quantum standards.
Ark Invest called the risk long-term, not imminent. Michael Saylor has dismissed quantum fears as "overblown," saying developers will upgrade the protocol long before any real danger arrives.
