The statement makes two claims about Ethereum on the OKX exchange: 1) its price fell below $3,100, and 2) it registered a positive daily price change on the same day. This describes a common scenario in volatile asset markets where the daily low is below the opening price, but the price recovers to close above the opening price.While none of the provided sources contain historical data specifically for Ethereum, they are highly authoritative as they come directly from the OKX exchange. The sources for Tether and Solana demonstrate that OKX provides detailed historical price data, including the daily open, close, high, and low prices. This confirms that the data points necessary to verify both parts of the statement (the daily low and the open/close prices for calculating the daily change) are tracked and made available by the exchange.The scenario itself is highly plausible. For a volatile asset like Ethereum, it is common for the price to experience a significant intraday dip (the 'low') before recovering and closing higher than its opening price for that 24-hour period. This would be visually represented as a green candlestick with a long lower wick.Given that the financial event described is a frequent occurrence in cryptocurrency markets and the sources confirm that the OKX platform provides the exact type of data needed to observe such an event, it is highly probable that this has happened. The lack of direct evidence for Ethereum in the provided links prevents a 1.0 probability, but the strong structural evidence from the sources about OKX's data reporting makes the statement very likely to be true.
