ChainCatcher message, on-chain detective ZachXBT reminds users to strengthen account and fund security. He states that currently Yubico (security keys), Proton (email service), and Tutanota (email service) all have discount promotions. Proton supports Bitcoin payments, while Tutanota can use Monero (XMR) to purchase gift cards through official partner ProxyStore.

In addition, 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 fund storage as soon as possible.
