We strongly suggest you avoid Guardian Invest since it is a scam red-flagged by a reputable financial watchdog. You need to drop the plan to engage with the fraudulent platform, regardless of the enticing deals it offers.

Guardian Invest is not licensed, as evidenced by the warning from the Financial Conduct Authority (FCA), the UK financial regulatory body. The FCA has confirmed that Guardian Invest is a clone of an FCA-authorized firm and thus it is a fraudulent platform. You can refer here for the full warning.

An impersonation scam, Guardian Invest is very dangerous. Entrusting this platform with your funds and personal information could be financially and personally devastating, as there are no rules in place to prevent fraud or theft. To mitigate such risks, we highly recommend choosing a fully regulated broker.
