The Securities Division of the Washington State Department of Financial Institutions (DFI) has issued a warning about cryptocurrency investment scams after receiving a complaint from a resident about their investment in the Miami Foundation Equity Fund 005. The investor deposited funds through a Whatsapp group led by "Mark" and "Alice" on the now-defunct Vims.one platform, which promised over 100% returns on cryptocurrency deposits twice a week. Despite paying a 5% withdrawal commission, the investor has not received their funds. The scam used a name similar to the legitimate Miami Foundation, but the foundation was not involved. DFI has classified such cases as "advance fee fraud" and cryptocurrency investment scams using social media.
