Crypto Custody Simulator

A short, hands-on look at the difference between keeping crypto on an exchange and holding it yourself.

This is a simulation. No real money, no real cryptocurrency, no real accounts. Nothing here affects any real service or wallet.

Exchange collapses have repeatedly cost ordinary people money they thought was safe — often not from a lack of intelligence, but because self-custody has real friction that most people never learn until it's too late. This game gives you a safe place to feel the difference.

You'll sign up at an exchange and receive starter Satoshi — usually a few hundred to a thousand, with a rare chance of a full simulated Bitcoin — look at what the public ledger actually knows, create your own wallet, withdraw your coins to it, watch the exchange collapse, and then find out what happens when your wallet's device is lost and has to be recovered.

This isn't an argument against exchanges — they're convenient, offer fiat on-ramps, and provide regulatory protection in some places. The goal is to help you choose consciously, not to tell you which is right.
