Mistake one: leaving everything on the exchange where you bought it. Convenient, but it means you never actually learn to use a wallet — and you're fully exposed if that exchange has a bad day.
Mistake two: buying based on a chart someone posted, not because you understand what the asset does. If you can't explain a project in two sentences, you don't understand it well enough to hold it through a 40% drawdown without panic-selling.
Mistake three: skipping 2FA setup because 'it's just a small account for now.' Accounts get compromised at the size they are, not the size you plan for them to become. Set up real two-factor authentication on day one.
Mistake four: treating a recovery phrase casually — a photo in the cloud, a note in an unencrypted app. If that account or device is ever compromised, so is your wallet.
