HONEY'S CRYPTO WORD OF THE WEEK

CRYPTO WISDOM

Control needs a safety net

Self-custody can remove an intermediary, but it also removes the reset button. Independence is valuable only when you pair it with backups, careful verification and a plan for mistakes.

STAY SAFE

Security first: guard the keys

Never type a private key or recovery phrase into a website, chat, “support” form, or screen-share app. Legitimate wallets and exchanges will not ask for it. Bookmark official sites yourself, and treat any urgent request to “verify” a wallet as a scam until proven otherwise.

NEW TO CRYPTO?

Your beginner step this week

Spend 20 minutes practicing account security: write down the difference between a password, recovery phrase and private key, then confirm that your wallet backup is offline, complete and stored somewhere only you can access.
