## Questions

### Is this course about building an agent?

No. It is for buyers and reviewers. It teaches what you need to read a listing and question a vendor. It does not teach code.

### Does the course tell me which wallet to pick?

No. This site never calls a wallet the best or the safest. The course shows how to compare wallets on facts that each vendor's docs state.

### What does the certificate of completion mean?

It is a certificate of completion from this site. It records that you passed the exam. It is not a professional credential, an audit or advice.
