Fact Check
The assessment is based on strong, consistent evidence from multiple highly relevant and authoritative sources. The primary source from Arkham, a blockchain analytics firm, directly addresses the topic of dormant Bitcoin addresses from 2009 awakening. This is corroborated by two separate news reports which, while from the same outlet, cite a specific on-chain monitoring firm (OnchainLens). These reports explicitly and consistently state that a 'Satoshi-era' wallet, inactive for '15 years', moved '50 BTC'. Every key detail of the statement is directly supported by these sources. There is no conflicting evidence among the provided materials; the sources deemed irrelevant pertain to traditional banking or general state policies and do not contradict the claim. The convergence of information from a primary analytics firm and news reports citing on-chain data provides high confidence in the statement's truthfulness.

Summary

A Casascius-linked Bitcoin wallet inactive for more than 13 years transferred 2,000 BTC valued at about $180 million on Dec. 7, according to CoinDesk. These coins had remained unmoved since 2011–2012, when BTC traded below $15. The transfer’s purpose is unknown and highlights the rarity of significant movements from early Bitcoin cold storage wallets. Casascius coins, created by Mike Caldwell between 2011 and 2013, embedded private keys in physical coins sealed with tamper-evident holograms, serving as offline cold storage until halted by U.S. regulatory intervention.
