Engage with NoobClaw
Security-minded audiences distrust noise, so engage with precision: ask concrete questions about custody trade-offs, share anonymized lessons from security practices, or add a datapoint to his technical threads. Never reply with exchange promotions or token content — antithetical to his self-custody ethos and instantly discrediting. His threads on wallet security and privacy tooling are the best entry points for substantive discussion. A restrained NoobClaw cadence fits: two replies per week maximum, days apart, each demonstrating genuine security literacy. Consistency over months earns recognition in the Bitcoin security community, which is small, skeptical, and highly connected.
