The advancement of 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) may face risks due to their owners being unable to migrate the keys to more secure cryptographic algorithms, potentially due to breakthroughs in quantum computing over old encryption technologies. This could lead to some bitcoins previously considered permanently lost being reintroduced into circulation, thereby changing the narrative of scarcity. Although Bitcoin developers can protect active wallets through protocol upgrades, the network's adaptability is also sufficient to meet the challenges of the quantum era, but old wallets may become more vulnerable targets for future attacks, posing new challenges to the security of the Bitcoin network.
