El Salvador recently moved to secure its national Bitcoin holdings. The country’s National Bitcoin Office (ONBTC) announced it has split its nearly 6,300 Bitcoins, worth around $680 million, into 14 separate digital addresses. This action aims to make El Salvador’s crypto reserves safer from potential future quantum computing threats. However, experts suggest being truly “quantum-proof” might still be a long way off.
The ONBTC explained this strategic shift over the weekend. They want to strengthen the security of their cryptocurrency holdings. By dividing their stash of almost 6,300 BTC across many blockchain addresses, they hope to lessen the dangers posed by quantum computing. While the move is forward-looking, specialists note that such threats are still many years away.
In a statement posted on X, the ONBTC explained its reasoning. Before this change, all the funds were kept in one address. This was done for transparency. Now, however, the Bitcoin is spread across 14 new, unused addresses. Each of these new addresses holds a maximum of 500 BTC.
This new setup significantly reduces the risk if an attack were to happen. Public keys, which are vital for security, are only shown when funds are spent. At that exact moment, they could become vulnerable to quantum algorithms. For example, Shor’s algorithm could potentially break the ECDSA cryptography that protects Bitcoin.
“Before, a single address was reused for more transparency,” the office stated. “This constantly exposed public keys. In theory, it gave a quantum attacker unlimited time to discover private keys.”
The ONBTC added that “The measure aligns with best practices of Bitcoin management and prepares for advances in quantum computing.” They also stressed that it “strengthens the integrity and future protection of El Salvador’s National Strategic Bitcoin Reserve against constantly evolving technological threats.”
El Salvador is moving the funds from a single Bitcoin address into multiple new, unused addresses as part of a strategic initiative to enhance the security and long-term custody of the National Strategic Bitcoin Reserve. This action aligns with best practices in Bitcoin…

Adam Back, a key figure in Bitcoin and CEO of Blockstream, praised El Salvador’s decision on X. He called it “good practice.” He highlighted the benefit of dividing funds into multiple UTXO (unspent transaction outputs) instead of repeatedly using one address.
Current blockchain data shows El Salvador’s reserves stand at 6,284 BTC. Under President Nayib Bukele’s leadership, the nation claims to buy one Bitcoin daily. However, a July report from the International Monetary Fund (IMF) indicated that the government had not purchased more Bitcoin since February, following a loan agreement.
While this diversification improves security and privacy today, it may not make the reserves entirely “quantum-proof” once such technology fully develops. The Bitcoin network itself might need future updates to handle these potential threats, as noted by CoinDesk. Experts at Bernstein estimate that an effective risk to Bitcoin from quantum computing is still “decades away.”
This bold action positions El Salvador, under President Bukele, as a leading example. It shows how a country can proactively manage its sovereign cryptocurrency holdings in a changing technological world.
