The assessment is based on highly authoritative and relevant evidence directly from the OKX exchange. The most crucial source is the BTC to USD converter on the official OKX website, which shows a Bitcoin price of $89,989.90. This figure is extremely close to the $91,000 value mentioned in the statement, differing by just over 1%. In the highly volatile cryptocurrency market, it is very common for an asset's intraday high (the peak price reached during a trading session) to be higher than a specific price snapshot. Given a documented price so near the target, it is highly probable that the price briefly touched or surpassed $91,000. A second highly relevant source, the USD to BTC converter page, is noted to contain historical high and low data, which is the exact type of information needed for definitive verification, lending further credibility to the claim's verifiability on the platform. The other sources are either irrelevant to Bitcoin's price or are general pages that don't contradict the claim. The lack of conflicting evidence, combined with the strong, direct evidence from the most authoritative source possible (the exchange itself), makes the statement very likely to be true.
