The claim is directly and precisely confirmed by 'BTC 突破 78000 USDT,24H 涨幅 1.66%' (Odaily, 2026-05-21T00:53:17Z), which reports the exact price of 78,006.1 USDT and the exact 24H gain of 1.66% from OKX market data. This timestamp aligns tightly with the collected_at value of 2026-05-21T01:05:22Z. PANews independently corroborates the 78,006.10 USDT price on OKX at the same moment, though its reported intraday gain differs (0.71%), likely due to a different calculation window. Two additional sources confirm BTC remained near 78,000 USDT on OKX later in the same day. The minor discrepancy in the gain percentage across sources is attributable to different 24H reference windows and does not undermine the core claim. Overall, the evidence strongly supports the claim.
