In terms of AI-related developments, there has been no direct impact from Powell's announcement on AI tokens. However, the general market sentiment influenced by the Fed's statement could indirectly affect AI-related tokens such as SingularityNET (AGIX) and Fetch.AI (FET). For instance, AGIX experienced a minor dip from $0.80 to $0.78, while FET saw a decline from $1.20 to $1.15 within the same timeframe (Source: CoinMarketCap, March 19, 2025, 14:05-15:05 UTC).

This suggests that AI tokens are likely to follow the broader market trends driven by macroeconomic news. Potential trading opportunities in the AI/crypto crossover include monitoring the performance of AI tokens in relation to major cryptocurrencies and adjusting trading strategies based on these correlations. AI-driven trading volume changes were minimal, with no significant shifts in trading algorithms or strategies directly attributable to the Fed's announcement (Source: Kaiko, March 19, 2025, 14:05-15:05 UTC).
