7-in-7 Digest issue dated 2026-10-08: Address poisoning is the scam of the season; Hardware wallets keep getting cheaper; Revoke approvals monthly; Passkeys and hardware keys replace SMS.

1. Address poisoning is the scam of the season

Attackers send dust from look-alike addresses so you copy the wrong one from history. Action: copy addresses from your wallet app, never from transaction history, and verify the first and last six characters on the device.

2. Hardware wallets keep getting cheaper

Entry devices now cost less than a dinner out. Action: anyone with more than a month's salary in crypto has no excuse — Top 7 Wallets.

3. Revoke approvals monthly

Old token approvals are an open door. Action: visit revoke.cash with each wallet and clear anything you don't recognise.

4. Passkeys and hardware keys replace SMS

Exchanges are rolling out passkeys. Action: switch 2FA from SMS to an authenticator app or hardware key today.

5. Liquid staking governance matured

Dual-governance and withdrawal queues reduce the risk profile of major LSTs. Action: run the numbers in our staking calculator before choosing between native and liquid staking.

6. Card rewards are a cycle indicator

Issuers raise cashback in bull markets and cut it in bears. Action: treat card rewards as a promo; compare on Top 7 Crypto Cards.

7. Reader question of the week

"Do I owe tax on a wallet-to-wallet transfer?" No — moving coins between your own wallets is not a disposal. Label it as such in your tax tool to avoid phantom gains.
