The assessment is based on overwhelming and consistent evidence from multiple high-authority sources. Several sources provide direct confirmation of the statement. One crypto news article explicitly states that Ethereum's all-time high was $4,950, which is substantially greater than the $2,100 threshold. Another news source from a major cryptocurrency exchange platform directly reports that Ethereum's price surpassed 2,100 USDT (a stablecoin pegged to the US dollar). Additionally, a page from another major exchange confirms an all-time high equivalent to well over $2,100.This direct evidence is strongly corroborated by five different financial data providers, including multiple international versions of a major financial portal and a prominent finance website. The summaries of these sources indicate they contain comprehensive historical price tables that can be used to verify this specific price milestone. The high number of credible, primary data sources that can be used for verification reinforces the statement's status as an established financial fact.There is a complete lack of contradictory evidence across all provided sources. The unanimity among financial data portals, major exchanges, and news outlets supports the conclusion with a high degree of confidence.
