On September 28, 2025, Arkham Intelligence analysts reported a transaction from an address that had been inactive since 2013. Its owner transferred 400 BTC, equivalent to approximately $44 million at the current exchange rate. The funds were divided into several 15 BTC installments and sent to new wallets.
According to Lookonchain, the initial deposit to this address occurred approximately 15 years ago through mining. The identity of the owner remains unknown, as does the purpose of the transfer. Nevertheless, the very fact that such a long-standing wallet was activated has sparked interest among experts.
During the period of inactivity, the price of Bitcoin increased almost 830-fold—from $135 to over $111,000 at the time of the transaction. Analysts believe such movements may signal that long-term holders are beginning to lock in profits amid the rising price of the leading cryptocurrency.
This event is just one of several recent examples of so-called "dormant" addresses awakening. In September 2025, another owner transferred 1,000 BTC, which had been stored in a wallet since 2014. Initially worth less than $1,000, at the time of the withdrawal, its value exceeded $116 million.
Also that month, an address with a balance of 444 BTC (approximately $50 million) became active. At the same time, one major investor decided to reallocate capital and exchanged a significant portion of his Bitcoin for Ethereum, increasing his ETH portfolio to $4 billion.
Also worth noting is the high-profile deal of July 2025: Galaxy Digital sold over 80,000 BTC, presumably belonging to an early Bitcoin participant. The deal was valued at over $9 billion.
Such cases demonstrate that long-term investors' interest in the market remains strong and intensifies during periods of renewed price highs. Analysts note that the entry of dormant wallets into the market often coincides with periods of rapid cryptocurrency growth.
Recent Ethereum movements are also worth mentioning: in September, it was reported that whales transferred over $785 million worth of coins after an eight-year hiatus. These events highlight a trend: long-term holders are gradually becoming more active in response to the growth of the crypto market capitalization.
