ZetBull is a crypto investment scheme that offers various investment plans promising up to 6,500% (!!!) returns. That sounds like a bad joke for particularly greedy or stupid investors, right? ZetBull is massively marketing its Crypto Investment plans via Telegram and social media. The operator is ZetBull Limited, a UK-registered company founded by Richard Walton in December 2020 with a purported fully paid-up share capital of GBP one million. The FCA has issued a warning against ZetBull.
