The statement is well-supported by the provided sources. Multiple sources, including Blockchain.news, MEXC, and KuCoin, confirm that the entity '7 Siblings' made a substantial purchase of approximately 12,800 ETH for around $31 million. This establishes the entity's identity and its significant buying activity during the specified market period.The key evidence supporting the full claim comes from the Bitget article, which is rated as highly relevant. It explicitly states that the '7 Siblings' entity, along with another wallet, collectively spent $57.44 million on Ethereum. This figure directly corroborates the "more than $57 million" part of the statement. The total ETH amount of 24,139 at a cost of ~$57.44M results in an average price of ~$2380 per ETH, which aligns with the market dip context described across the articles.The only ambiguity arises from the word "collectively" in the Bitget report, which could suggest that '7 Siblings' was not the sole purchaser. However, no source contradicts the total figures, and given that '7 Siblings' is a known whale *group* (implying multiple associated wallets), it is highly plausible that the full amount is attributable to the entity as a whole. The weight of the evidence confirms a massive accumulation event by this entity, with the specific financial figures from the statement being directly present in the source material.
