The assessment that the statement is likely true is based on strong, consistent, and authoritative evidence from the primary sources provided. The most compelling evidence comes from multiple currency conversion pages directly on the OKX exchange website. The summaries for the Solana to Canadian Dollar (CAD), Uzbekistani Som (UZS), and Vietnamese Dong (VND) pages all explicitly state that Solana's all-time high price on the platform, when converted, was well in excess of the $140 USD threshold. This provides powerful, corroborating evidence from multiple, highly authoritative sources (Authority: 0.95).Furthermore, the most relevant source listed is the primary Solana price page on OKX itself. Its summary indicates that it provides historical charts, which would serve as direct, definitive proof of the price history on the exchange. The existence of this primary data source, combined with the explicit confirmations from the other OKX currency pages, creates a very strong case in favor of the statement's truthfulness.There is no contradictory evidence among the provided sources. Less relevant sources, such as the one for the Pakistani Rupee or the aggregated TradingView chart, do not challenge the claim; they simply lack the specific historical data for the OKX exchange needed for verification. The cumulative weight of the high-authority, high-relevance sources strongly supports the conclusion that Solana's price did exceed $140 on OKX.
