The assessment is based on strong, consistent evidence from multiple relevant sources. Two news articles (from blockchain.news and ainvest.com) directly and explicitly support the statement. The blockchain.news article is particularly credible as it has high authority and cites on-chain analytics firms Lookonchain and Arkham as the primary source of the data. It specifies that Arthur Hayes sold 520 ETH, 2.62M ENA, and 132,730 ETHFI for a total of $2.52 million. This directly confirms the key elements of the claim: the sale was made by Arthur Hayes, it included Ethereum and other altcoins, and the total value exceeded $2.5 million.The Arkham research, while describing a different transaction (an NFT sale for $6.06M), confirms that Hayes is engaged in large-scale sales involving Ethereum-based assets, lending general credibility to the idea of him making such a move. The sources that seem to contradict the statement are of low relevance; they discuss Hayes' general intention to buy during dips or his other holdings and purchases, which do not negate the specific sale in question. The remaining sources are irrelevant. Given the direct, corroborating evidence from credible secondary sources citing primary data, and the lack of any direct contradictory evidence, the statement is very likely to be true.
