TechFlow reports, on November 29, on-chain investigator ZachXBT advised users to strengthen account and fund security. He noted that Yubico (security keys), Proton (email service), and Tutanota (email service) are currently offering discounts. Proton supports Bitcoin payments, while Tutanota allows purchasing gift cards via its official partner ProxyStore using Monero (XMR). Additionally, select hardware wallet products from brands Trezor and Ledger are also on promotion. ZachXBT recommended avoiding Gmail or SMS-based 2FA (two-factor authentication) and switching to security keys or storing funds in hardware wallets as soon as possible.
