Ethereum ICO whale moves 10,000 ETH after 10-year dormancy

On-chain data shows an Ethereum address that received tokens during the platform's initial coin offering transferred roughly 10,000 ETH, about $23.1 million at current prices, to a newly active address late Tuesday evening.

The source address, shown on-chain as 0xCD5…7a336, first received the ether on July 30, 2015 after participating in the ICO with an initial outlay of roughly $3,100. The holding has risen in value by about 7,465 times since that distribution.

Blockchain records indicate the transfer went to a previously unused wallet. There is no visible interaction in the transaction history that explains the transfer, such as calls to decentralized applications, and the owner's intent is not publicly known.

Market participants and on-chain analysts monitor large transfers from long-dormant wallets because such movements can precede sales, though a transfer alone does not confirm any sale.

The transfer follows a pattern of dormant ICO-era wallets reactivating during the 2025 bull run. In September, a separate longtime inactive ICO wallet moved 150,000 ETH after about three years of inactivity.

Ethereum traded around $2,335, up 1.9% in the 24 hours leading up to 12:50 a.m. ET on Wednesday, remaining below the $4,946 all-time high recorded last year.

On-chain researchers and analytics firms track addresses created during the 2014–2015 ICO because their activity can affect expectations for available supply. While on-chain data shows transfers and balances, tying an address to a person or organization requires off-chain information or legal processes.

There was no immediate, clear impact on market prices visible in on-chain data. Observers are likely to watch the receiving address for subsequent actions such as conversion to other tokens, movement to trading venues, or other transactions that could indicate a sale.
