In terms of AI-related news, there have been no direct AI developments tied to this rumor. However, the market's reaction to potential policy changes can be correlated with AI-driven trading strategies. For instance, AI trading algorithms might have contributed to the rapid price movements observed, as they often react quickly to news and sentiment shifts. The correlation coefficient between Bitcoin and major AI tokens like SingularityNET (AGIX) increased from 0.6 to 0.75 within the hour following the rumor, suggesting a stronger linkage between AI and crypto markets (CoinMetrics, March 19, 2025).
