Reports on the chain indicate that about 6.7 million Bitcoin currently reside in quantum-risk addresses. These signs have not moved for many years, and some have not moved for more than a decade. Part of this coin is also believed to belong to Satoshi Nakamoto.
Currently, this amount is the most important in the history of financial crime.
Bitcoin Exposure is not fixed
New whitepaper from Google Quantum AIpublished on March 30, 2026, shows the actual measurements of Bitcoin’s rate of increase for the first time.
The study shows 100,000 Bitcoin addresses are subject to what is known as an at-rest attack, meaning that the most powerful computers can access their private keys without the owner having to initiate a transaction.
In total, these addresses hold approximately 6.7 million BTC.

Why Old Bitcoin Addresses Are So Dangerous
The most widely disclosed funds are those locked in Pay-to-Public-Key documents since the first period of Bitcoin mining, which is called the Satoshi period of 2009 and 2010. These records store the public key directly on the blockchain, visible to everyone.
A supercomputer with Shor’s algorithm can use the public key to find the corresponding private key and extract the address.
Around 6,000 official addresses, a prison of 50 BTC addresses are emerging, each holding exactly one prize for the first mining, many of which have not been touched since the years of Bitcoin.
“The progress of the number of Bitcoin foundation builders is important, because there are parts of the Bitcoin community – whether it should be or not – that are concerned about the number of volumes and want to see it seriously and be answered. As more information comes out and people see it being used, this will be good,” said Matt HouganChief Investment Officer at Bitwise, BeInCrypto Expert Council.
A problem that cannot be patched
Unlike active wallets, residential addresses cannot be uploaded. They cannot migrate to post-quantum cryptography. They represent a fixed, forever-visible target that will only grow more dangerous as quantum hardware advances.
Google researchers estimate that around 1.7 million BTC are locked in P2PK scripts, and that the amount at stake for all types of scripts can reach 6.9 million BTC when the address is reused.
Google’s paper says that the community and regulators will soon be faced with an unprecedented question: what happens to this money when the quantum computer automatically takes it?
The options being discussed range from the destruction of vulnerable protocols to rules governing recovery: a concept the paper calls digital rescue. There are no easy answers, but the planning window is closing.
