The advances in quantum computing technology may redefine the traditional notion that "lost coins" in Bitcoin cannot be recovered. The article points out that some early generated and long-abandoned wallets (such as Satoshi Nakamoto's wallet), due to their owners' inability to migrate their keys to a more secure cryptographic algorithm, may face risks from quantum computing breakthroughs in old encryption technology. This could potentially allow some bitcoins previously thought to be permanently lost to re-enter circulation, thereby changing the narrative of scarcity. Although Bitcoin developers can protect active wallets through protocol upgrades, the network's adaptability is sufficient to meet the challenges of the quantum era, older wallets may become easier targets for future attacks, posing new challenges to the security of the Bitcoin network.
