FAQ

Do I need a cold wallet to take the course?

No. You can watch first and decide later; module 4 teaches how to choose one and buy it safely.

Will I have to show my seed or my wallets?

Never. No one from the course will ask for your seed, password or access to your wallets. Anyone asking in the course's name is a scammer.

How do I get access?

Right after buying on Hotmart, go to autocustodia.tradewithrenato.com with the email you used. You'll get a sign-in link by email — no password needed.

How long does it take?

About 5 hours of video, plus texts and quizzes. Go at your own pace — the platform keeps track of the lessons you've finished.

Does it work on my phone?

Yes. It opens in the browser on your phone, tablet or computer, with nothing to install.

Does the course tell me where to invest or how to earn yield?

No. It's an educational course. Module 7 explains how DeFi yield works and the risks of each type, with no investment advice.

Is there a certificate?

Yes. When you pass the final exam (30 case-based questions, 70% to pass), you get your certificate of completion by email in Portuguese, English and Spanish, with a verification code. See the sample at autocustodia.tradewithrenato.com/certificado/MODELO.

I live outside Brazil. Can I buy?
