TL;DR
- A Bitcoin wallet inactive for eight and a half years transferred 5,908 BTC valued at approximately $383 million.
- The funds were received in December 2017 when BTC was trading near $16,800, implying a gain of around 284% on the original $100 million capital.
- The Bitcoins moved to a new address with no known exchange link, so there is no evidence of a direct sale at this time.
A wallet holding Bitcoin for more than eight years without activity transferred its entire balance on Wednesday: 5,908 BTC valued at approximately $383 million. The transaction was detected by Lookonchain using data from Arkham and took place at 7:15 p.m. Eastern time on Wednesday. The source address, identified as “138EM…ReyiT”, deposited those funds in December 2017, when BTC was trading at around $16,800.
At that time, the position was worth approximately $99.6 million. At current prices, it stands at around $383 million, representing an approximate gain of 284%. The journey was not linear: the wallet endured the 80% crash Bitcoin suffered during 2018, withstood the collapse to $15,500 in November 2022 — when the position briefly turned negative — and did not move even when the cryptocurrency reached its all-time high of $122,000 in October 2025.
$383 Million in Bitcoin and No Confirmed Sale
The destination of the funds is the central point to analyze. The BTC did not arrive at a Coinbase or Binance deposit address, but rather to a new address with no known label, which rules out a direct sale on public markets. Analysts also identified a format change: the funds left an address beginning with “1”, the original Bitcoin format dating back to 2009, and arrived at one beginning with “bc1q”, a more recent and more cost-efficient type to operate.
This type of transaction can be explained by various reasons: custody upgrade, key rotation, asset liquidation, or preparation for an over-the-counter sale that bypasses public order books. Without a transfer to an exchange, no exit scenario can be confirmed.
Earlier in the same week, another wallet inactive for more than seven years moved nearly $188 million in BTC. Both cases drew attention in the market, as traders tend to interpret these movements as potential signals ahead of sales. However, the evidence available so far does not support that reading.
