Animate a simple curve: each buy is a step up, each sell a step down. Show why the first buyer gets the most coins per SOL, then reveal how a hidden first-buyer dumps on everyone.

When a coin launches it sits on a bonding curve — an automatic pricing machine. There is no order book and no human market maker. A formula decides the price.

How the price moves

  • arrow_rightEvery buy pushes the price up. Every sell pushes it down.
  • arrow_rightEarly buyers get the cheapest price. The earlier you are, the more coins you get per SOL.
  • arrow_rightAll the SOL people spend goes into the curve — the pool everyone buys from and sells back to.
  • arrow_rightWhen enough is bought (the curve fills, called "bonding" or "graduating") the coin moves to a real DEX like Raydium and the curve is done.

Why this matters for scams: because early buyers get coins so cheap, a scammer who secretly buys first can dump on everyone who buys after them. The entire rug-pull playbook is built on getting in before you do.
