Odaily Planet Daily News: On-chain detective ZachXBT reminds users to strengthen account and fund security. He stated that currently Yubico (security keys), Proton (email service), and Tutanota (email service) all have discount promotions. Proton supports Bitcoin payments, while Tutanota allows purchasing gift cards with Monero (XMR) through official partner ProxyStore. Additionally, hardware wallet brands Trezor and Ledger have some products on promotion. ZachXBT advises users to avoid using Gmail or SMS 2FA (two-factor authentication) and to switch to security keys or hardware wallets for storing funds as soon as possible.
