A dormant Satoshi-era Bitcoin wallet came back to life after 13 years, transferring its entire 909.38 BTC balance, worth about $84.6 million at current prices, into a fresh BTC address.
Onchain data from blockchain analytics firm Arkham Intelligence shows that the address first received Bitcoin (BTC) in 2013, when one coin was trading at less than $7.
By comparison, if, instead of buying 909.38 BTC, worth about $6,400 in 2013, the same amount had gone into a low‑cost S&P 500 index fund, it would be worth $37,000 today, after a gain of 481%.
Over the same 13‑year window, benchmark gold prices have risen about 150%; solid returns, but still dwarfed by the 13,900x Bitcoin increase.

Old whales are waking up
The dormant whale transfer comes after a revival of older wallets in 2024–25, when long‑dormant addresses, including 10‑plus‑year OG holders, have collectively moved more than $50 billion worth of BTC. Onchain data showed tens of thousands of those ancient coins were ultimately spent.
For investors, the human side of this story is almost as striking as the numbers. Holding through multiple 70%–80% drawdowns, the 2017 and 2021 market cycles, major exchange failures, contentious forks like Bitcoin Cash (BCH) and Bitcoin SV (BSV), and rolling regulatory crackdowns would have required unusual conviction (or, perhaps, the possibility of the owner losing their keys and only recently recovering access).
The Monday shift to a new address could be routine security hygiene, a change of custody or the first step toward eventual liquidation. Onchain analysts will be watching closely to see whether the funds flow to known exchange wallets.

Quantum risk and “exposed” UTXOs
Early holders may also be repositioning in response to a growing chorus of warnings about future quantum attacks on Bitcoin’s elliptic‑curve signatures, the cryptographic signatures Bitcoin uses to prove that someone with a private key authorized a transaction.
This is particularly pertinent for older UTXOs (the “unspent transaction outputs” that make up a wallet’s balance and represent individual chunks of BTC created by past transactions), which have already exposed their public keys.
While most cryptographers still see quantum computers as years away, recent research has urged the ecosystem to prepare migration paths to post‑quantum schemes, a risk that could motivate security-conscious OGs to move coins into newer setups even if they are not yet selling.
