The statement is overwhelmingly supported by a strong consensus across multiple, highly relevant sources. Six of the provided sources, ranging from medium to very high authority (Phemex, Coinbase, ZyCrypto, U.Today, MEXC, Yellow.com), all report on the same event with remarkable consistency in the core details: a wallet from a very early period in Bitcoin's history ('Satoshi era'), dormant for approximately 13 years, moved a substantial amount of Bitcoin (specifically 909 BTC) valued at around $84-85 million. The minor variation in the dollar value is expected due to normal price fluctuations. The sources that do not support the claim are either irrelevant to the specific event (the Wikipedia article on Satoshi's personal wallet, the Koinly blog, the book review) or have very low authority (the Facebook post, which still corroborates the claim). There are no direct contradictions from any credible source. The high degree of corroboration across several independent crypto news outlets and exchanges makes it highly probable that the statement is true.
