The $145 billion math: Why bitcoin’s quantum threat is manageable, not existential

Recent progress in quantum computing has reignited a long-standing concern for bitcoin .

A sufficiently powerful cryptographically relevant quantum computer could, in theory, break bitcoin’s elliptic curve signatures, exposing coins with visible public keys, particularly early Satoshi-era wallets, according to bitcoin analyst James Check.

Quantum doomsayers warn that this would unleash a flood of supply and crash the market. The numbers suggest otherwise.

The threat of quantum computing is not in question.

Roughly 1.7 million $BTC sit in Satoshi-era addresses that could be vulnerable under such a scenario. That is about $145 billion at current prices in potential sell pressure, which sounds catastrophic, but is in fact manageable.

During bull markets, long-term holders (investors that have held bitcoin for at least 155 days) routinely distribute between 10,000 and 30,000 $BTC per day. At that pace, the entire Satoshi-era supply equates to roughly two to three months of typical profit taking. In the most recent bear market, more than 2.3 million $BTC changed hands in a single quarter, exceeding the full quantum “target,” with no systemic collapse.

In addition, monthly exchange inflows approach 850,000 $BTC. Derivatives markets cycle through notional volumes equivalent to the entire Satoshi stash every few days. What appears massive in isolation becomes relatively ordinary when set against bitcoin’s existing liquidity and turnover.

A sudden, concentrated release would still matter. It would likely drive volatility and could trigger a prolonged downturn, according to Check. But even that scenario assumes economically irrational behavior. Any actor capable of accessing such a trove would be incentivized to distribute gradually, likely hedging through derivatives to minimize slippage and maximize returns.

Bitcoin markets routinely absorb supply on the same order of magnitude as the P2PK era coins. The timeframe is measured in months, not years.

The real issue is not mechanical sell pressure. It is governance. The bigger issue is potentially freezing the Satoshi coins, through BIP-361, then letting everything play out as it should.
