The assessment is primarily based on a single, highly authoritative and relevant source. A social media post from CoinGecko, a major cryptocurrency data aggregator, provides a primary report directly stating that the total crypto market capitalization lost $100 billion within a one-hour period. This event is more rapid and severe than the one described in the statement, but it fully supports the claim that such a decrease occurred within a 12-hour period. If the market lost $100 billion in one hour, it axiomatically lost that amount within any 12-hour window containing that hour.The vast majority of the other sources provided are irrelevant to the claim. They focus on individual company stocks (Coinbase, Rockwool, MicroStrategy), different markets (S&P 500, U.S. housing), other commodities (gold, crude oil), or are general encyclopedia entries that do not contain specific, time-sensitive data. None of these sources contradict the primary evidence.Given the strong, direct, and uncontradicted evidence from a credible primary source, the statement is assessed as likely true with a high degree of confidence.
