The assessment is based on a combination of direct evidence and strong contextual information. The Schwab Market Update is a highly authoritative and relevant primary source that explicitly shows a cryptocurrency's price and its change around the time of the U.S. market open. This directly supports the premise that cryptocurrency prices are actively changing and being reported at that specific time.Furthermore, an educational guide from the Bitget cryptocurrency exchange provides the crucial context that cryptocurrency markets operate 24/7, independent of traditional stock market hours. This is a fundamental characteristic of the asset class. Given the thousands of different cryptocurrencies and their inherent volatility, it is statistically almost certain that at any given moment—including the U.S. market open—some will be experiencing price increases while others experience decreases due to varying market dynamics and investor activity. The statement is general enough ("some... while others...") that this normal market behavior makes it highly probable. While the provided sources do not offer a comprehensive list showing multiple cryptocurrencies with divergent price movements on a specific date, the combination of a high-authority source confirming the phenomenon for at least one crypto, coupled with the known 24/7 nature of the market, provides strong support for the statement's truthfulness. No sources offer contradictory evidence.
