According to Altcoin Daily, Japan "just crashed crypto" in a one-line post on X dated Dec 1, 2025 (source: Altcoin Daily on X, Dec 1, 2025). The post provides no corroborating details such as a policy announcement, exchange action, or market price data to validate the claim (source: Altcoin Daily on X, Dec 1, 2025). Given the absence of evidence in the post, traders should treat the headline as unverified and wait for confirmation from official Japanese channels or real-time market feeds before acting (source: Altcoin Daily on X, Dec 1, 2025).
