Advancements in quantum computing have brought renewed attention to potential vulnerabilities in bitcoin (BTC), currently priced at $77,596.36. According to bitcoin analyst James Check, a sufficiently advanced quantum computer could theoretically compromise the elliptic curve signatures that protect bitcoins with publicly visible keys, particularly those from the early Satoshi-era wallets.
While some fear this scenario would trigger an avalanche of supply and devastate the market, data suggests otherwise. The potential sell pressure from approximately 1.7 million BTC in vulnerable Satoshi-era addresses—worth about $145 billion today—is significant but not insurmountable.
During bull markets, long-term bitcoin holders typically distribute between 10,000 to 30,000 BTC daily. This rate means that the entire supply of early bitcoins could be liquidated over two to three months through regular profit-taking. In contrast, during the most recent bear market, more than 2.3 million BTC changed hands in a single quarter without causing systemic failure.
Moreover, monthly exchange inflows are around 850,000 BTC, and derivatives markets process notional volumes equal to all early bitcoins every few days. What seems daunting in isolation becomes less so against the backdrop of bitcoin’s existing liquidity and turnover.
A concentrated release could increase volatility and potentially lead to a downturn, as Check notes. However, this scenario assumes irrational actions by those controlling such wealth. A rational actor would likely stagger the release and hedge through derivatives to maximize returns while minimizing market impact.
The Bitcoin ecosystem has historically absorbed similar volumes of supply from P2PK-era coins within months. The real challenge lies in governance. Specifically, freezing Satoshi bitcoins using BIP-361 and allowing natural market processes could be a more effective solution than focusing solely on sell pressure.
