I built TestiMoney (https://testimoney.xyz) - a social experiment where posting costs money and your message's value decays over time.

  How it works:
  - Pay $10+ to post a 180-character message
  - Value decays 1-10%/hour (rate increases with viewer count)
  - Users can like/dislike to affect value (+/- 5%)
  - Super Likes ($1-50) add 100% of payment to value
  - Only 100 messages exist at once - lowest value gets archived

  Tech: Next.js, Fastify, PostgreSQL, Redis, WebSockets, Stripe

  The decay creates an interesting dynamic: popular times mean faster decay for everyone, creating natural pressure on the "market."

  I'm curious to see emergent behaviors - will people coordinate? Will whales dominate? Will anyone actually use this?

  Built this as a weekend project that got out of hand. Feedback welcome.
