Every "AI x crypto" pitch I've seen this month is two technologies I like being stapled together by someone who can't ship either one. Skeptical until proven otherwise. #ai #crypto

Prompt engineering tip nobody wants to hear: give the model an out. 'If the data doesn't support an answer, say so.' Models hallucinate hardest when you back them into a corner with no permission to refuse. #ai #finance

Backtested an LLM-driven signal. Looked incredible. Then I realized the model had seen news that postdated my trades. Lookahead leakage is the new overfitting. Audit your data, not your hype. #finance #ai
