A bitcoin address that had not spent a coin in eight years moved 5,908 BTC worth about $383 million on Thursday, data shows.
The wallet took in the coins when bitcoin traded at around $16,000, a level the market saw in December 2017 and early January 2018, within weeks of a cycle peak near $20,000.
The stack cost roughly $100 million then and is worth about $383 million now, a gain of about 284%. It was worth $726 million at bitcoin’s lifetime in October 2025.
The entry date is what makes the holding unusual. Bitcoin fell about 80% through 2018 to near $3,200. It recovered to $69,000 in 2021, then collapsed to about $15,500 in November 2022, which briefly put this position underwater five years after it was built.
The wallet stayed shut then, and again last year when bitcoin cleared $122,000, roughly seven times the entry price. It is opening now, with bitcoin near $64,800 and about half the 2025 high behind it.
