Then prove it: a 2-question quiz. The lesson marks itself complete at 100%.
What you need
A phone you control, with a lock screen.
Pen and paper (metal later, if the amount grows).
Twenty undisturbed minutes.
Choosing
For a first wallet, choose a well-known, open-source, non-custodial mobile wallet. The signs of a good one: it shows you a 12- or 24-word seed phrase at setup, it is open source, it has been around for years, and it lets you set your own fee. Avoid any app that asks you to create an "account" with email and password; that is a custodian.
Steps
Check your work
You have received and sent. You know where the words are. If you deleted the app right now, you could restore it from the paper. That is a working wallet.
CHECK YOURSELF
