Eight long-inactive Bitcoin wallets moved a combined 80,000 BTC in July 2025, according to Tom’s Hardware. The nearly 14 million percent increase cited in the report applies to one 10,000-BTC tranche—not to all 80,000 BTC—and describes a theoretical change in value, not a verified sale or realized profit.
What happened to the dormant Bitcoin?
Tom’s Hardware reported that two wallets containing 10,000 BTC each moved their holdings first, followed several hours later by six more wallets holding 10,000 BTC apiece. The reported destination addresses were new. The transfers put 80,000 BTC in motion in total, valued at about $8.6 billion at the time of the report.
The wallets’ beneficial owner was not identified. The reporting describes Bitcoin moving between addresses; it does not establish who controlled the destination addresses or why the transfers occurred.
What does a 13 million percent increase mean?
The nearly 14 million percent figure in Tom’s Hardware refers to a specific 10,000-BTC tranche, using an approximate purchase price of $0.78 per BTC on April 3, 2011. At that basis, the tranche would have cost about $7,800. The report compared it with a Bitcoin price of roughly $108,000 at the time, producing an enormous theoretical increase in value.

A percentage increase compares a starting value with an ending value; it is not itself a dollar profit figure. The cited return is a historical comparison based on the report’s approximate prices. It is not inflation-adjusted, and it does not show what the holder received by selling.
Why is the estimate for all 80,000 BTC lower?
The same Tom’s Hardware report separately estimated a nearly 4 million percent return for the full 80,000 BTC, saying the aggregate initial cost was below $210,000. That calculation uses a different, broader holdings total and cost basis than the 10,000-BTC tranche comparison. The two percentages therefore describe different calculations and should not be treated as contradictory or interchangeable.

The report’s aggregate cost basis is an estimate; the available reporting does not independently establish the holder’s purchase records or exact acquisition prices for every wallet.
Did the owner sell the Bitcoin?
The reports do not establish a sale, cash-out, or conversion of the full balance to fiat. A blockchain transfer shows Bitcoin moving from one address to another; by itself, it does not prove that the recipient is a buyer, that beneficial ownership changed, or that the coins were sold. The holder’s identity and motive also remain unknown.

Another dormant-wallet transfer reported in July 2025
This 80,000-BTC event is separate from a later July 2025 movement reported by The Block: a wallet moved 3,962 BTC after more than 14 years of inactivity. The Block likewise reported that the owner was unknown; interpretations that the movement meant a sale were speculation. That transfer should not be added to the 80,000 BTC or used to infer the same owner or motive.
