A Bitcoin address that had been dormant for over 14 years suddenly reactivated on August 6, 2026, moving 49.97 BTC worth approximately $3.23 million.

According to monitoring by Galaxy Research, the address beginning with "1EBz" first received the Bitcoin on July 16, 2011, when BTC traded under $15. The funds sat untouched until 20:14 UTC on August 6, 2026, when a single transaction swept the entire balance to a new address in block 961331.

The full address is 1EBzWeno4frVz5hKp3LvVRpN84cpfJzYjL.

At roughly $10 per coin at the time of acquisition, the 49.97 BTC cost approximately $500 in mid-2011. With BTC priced near $65,000 today, the position has grown to $3.23 million—a 634,347% gain. That return profile is characteristic of Bitcoin's earliest years, when the asset was a thinly traded experiment rather than a $1.3 trillion market. Few holders have kept their funds—or their private keys—for that long.

The destination wallet subsequently sent funds to a FalconX-labeled wallet, according to data from Arkham Intelligence. FalconX is a prime broker serving trading firms and institutions, not a retail exchange. The connection does not confirm a sale, but it does raise the possibility that whoever controls the coins is consolidating them or positioning them closer to a venue where they could be sold or used as collateral. When coins route through prime brokers rather than directly to a retail exchange, on-chain analysts typically watch for follow-on transfers to known exchange hot wallets or over-the-counter desks—patterns that can help distinguish custody or collateral arrangements from active liquidation.

The reactivation of old Bitcoin wallets is not an isolated event. Satoshi-era whales have repeatedly made headlines when long-dormant stashes shift. In 2023, a whale moved $11 million in BTC after 12 years of inactivity, and another ancient stash changed wallets after the same period. In 2024, nearly 50,000 BTC worth $2 billion shifted after sitting idle since 2013, with analysts attributing the movement to exchange or custodian rebalancing rather than an individual early adopter. Bitcoin whales woke up repeatedly throughout 2025 and moved billions.

In most of those cases, the destination pointed to professional infrastructure rather than a private holder liquidating assets.

The key metric analysts use to track such events is "Coin Days Destroyed," also known as Satoshi Days. Every day a Bitcoin remains unmoved, it accrues one "day" of age. When the coin finally moves, all accumulated days are destroyed at once. A single transfer from a 2011 wallet erases more than 5,400 days per coin—a significant figure that signals an old balance changing hands.

A large movement can indicate that an early adopter is taking profits or simply relocating coins for security or custody reasons. The metric confirms that a transfer occurred but does not reveal the motive, which is why some traders factor these movements into their analysis. Long-term holders—the cohort defined by on-chain analytics firms such as Glassnode as wallets holding for 155 days or more—are tracked as a distinct category because shifts in their behavior are closely followed as a gauge of conviction among Bitcoin's earliest participants. With Bitcoin's total supply capped at 21 million coins, dormant balances from the network's first years represent a finite pool that has been gradually shrinking as early addresses either move or are presumed lost.

As of Friday, the BTC remained in the receiving address.
