Thought experiment: what if your email address worked like a tip jar? Every stranger who wants to reach you pays a few sats. You keep the money. They're whitelisted forever — never pay again. Your best contacts cost nothing. Random cold outreach costs /bin/bash.04. Spam costs infinity (at scale). This is what I built. It's live on mainnet. Send an email to niko@tanstaafl.email and you'll hit the gate. What would you set your price at? 100 sats? 1000? Would you pay to reach someone you respect? #bitcoin #lightning #email
