A Bitcoin wallet that has held 4,581.94 BTC since March 2020 sent its entire balance to five new addresses on Oct. 12, moving roughly $377 million a single transaction, according to blockchain data. The stash had sat untouched since it was funded more than six years ago.

The transfer confirmed in block 971,126 at approximately 18:37 UTC, with Bitcoin trading around $82,350 at the time. Four of the five receiving addresses got exactly 1,000 BTC each, while the fifth received the remaining 581.94 BTC. The transaction paid a fee of just 732 satoshis—the hundred-millionth-of-a-Bitcoin units known as sats—or about 60 cents. Bitcoin fees are calculated from a transaction's size and the prevailing demand for block space rather than the dollar value being moved, which is why a nine-figure transfer can clear for under a dollar.

As of block 971,279 on Oct. 13, none of the five addresses had spent anything, and it remains unclear who controls the wallet or where the coins are headed. Splitting a large balance across fresh addresses is a routine self-custody practice for holders managing privacy and key security.

From $40 Million to Nearly 10X

The wallet received its coins on March 3, 2020, in a transaction that split a 5,081.95 BTC balance three ways, sending 250 BTC to each of two other addresses. At roughly $8,830 per Bitcoin, the 4,581.95 BTC that landed in the wallet was worth about $40.5 million. The holding's value has since grown nearly tenfold.

The address stands as an example of patience. The coins sat through several market shocks after they arrived, beginning with the COVID-19 crisis, which started shortly after the wallet was funded. During that period, the stash fell from about $40.5 million to roughly $17.6 million.

Tesla's suspension of Bitcoin payments and China's mining crackdown followed in May 2021, cutting the wallet's value from about $291 million at its April peak to $131 million by June.

The collapses of Terra, Celsius and FTX in 2022 would have taken the holding down to about $71 million—a loss of approximately $239 million from its November 2021 peak—as the Federal Reserve's rate hikes also dragged the S&P 500 down about 25% and Bitcoin hit a two-year low.

Trump's tariff shock also crashed the markets. Bitcoin fell 54% from its record high of $124,728 to $57,735 before recovering to its current price. The wallet's value dropped from $571.5 million to about $265 million during that dip, but overall, holding has produced almost 10X in net gains since day one.

Dust Deposits and a Poisoning Attempt

The address has also collected dust over the years—transfers of a few hundred to a few thousand sats that cost almost nothing to send. Blockchain records show 22 such deposits between August 2020 and May 2026, ranging from 546 to 6,953 sats, or less than $6 each at current prices. Sixteen of them arrived in batch transactions that paid out to between 87 and 610 addresses at once. The deposits were trivial in value relative to the wallet's overall balance.

One deposit matches the pattern of address poisoning, a scheme in which an attacker generates an address that copies the first and last characters of a legitimate one, hoping someone will later copy it from a transaction history by mistake. On Jan. 28, 2025, an address beginning 18VpNbPc and ending pQ9x sent the wallet 600 sats, and it shares the first three and last four characters with the whale's address.

The look-alike was funded in a Nov. 12, 2024 transaction that paid out to 1,401 outputs at once, and it was emptied after sending that single payment. Every other sender used a bc1 address—the bech32 format introduced in 2017—which looks nothing like the wallet's legacy 18 address, one of the original address styles from Bitcoin's early years. The whale hasn't fallen for it.

A History of Dormant Whale Moves

Large holders of Bitcoin, known as whales, move their coins for a variety of reasons, including privacy and safety. Analysts and traders fear that moves like this one precede selling, as long-dormant holders feel tempted to realize significant gains. The blockchain shows every movement but never the motive, which is why analysts typically watch whether coins like these later surface in wallets linked to exchanges.

That said, this is not the first time dormant wallets have moved their coins. Back in July 2025, an entity moved 80,000 BTC that had sat untouched for 14 years, worth $8.6 billion at the time—the biggest daily movement of coins aged 10 years or more. Ten days later, a Satoshi-era wallet sent 40,009 BTC, about $4.7 billion, to Galaxy, which later said it had executed a sale worth roughly $9 billion for a Satoshi-era client.

As of Oct. 13, the original address holds 23,288 sats in leftover dust, about $19, while the five receiving addresses hold the full 4,581.94 BTC. Whether those balances stay put or move again is the signal onlookers will be watching next.
