A cryptocurrency scheme promising guaranteed mining returns has collapsed under federal investigation in Brazil, leaving thousands of investors without payments since last October.
Brazilian Federal Police and the Public Ministry are investigating MinerWorld on suspicion it operates as a pyramid scheme. The company's owner, Cícero Saad Cruz, also faces organized crime investigations in Mato Grosso do Sul and São Paulo. Federal agents raided MinerWorld's headquarters in Campo Grande after the investigations intensified.
Authorities in Mato Grosso do Sul found no evidence that MinerWorld actually mines bitcoin inside Brazil or anywhere else, despite the company claiming operations in Paraguay and China. The findings suggest the 12-month mining ROIs MinerWorld advertised to customers were never backed by real cryptocurrency operations.
The scheme began unraveling when investors stopped receiving payments. MinerWorld blamed the freeze on a theft—claiming someone stole 851 mined bitcoins from their accounts. The company disclosed this loss to investors in February, five months after it supposedly occurred. No proof of the theft has surfaced, nor has MinerWorld produced evidence it ever mined any cryptocurrency.
Court documents show Brazilian authorities opened their investigation in September, months before the theft claim. Yet MinerWorld continues insisting it operates legally in Brazil, despite never registering to offer securities and paying commissions for recruiting new investors—both violations of Brazilian law.
Authorities have frozen approximately $88.6 million across various accounts tied to MinerWorld. The seizure represents the bulk of investor deposits still in the company's possession.
MinerWorld's response to the financial crisis reveals the depth of the deception. The company told victims they would eventually receive their money, but asked for 24 months to repay promised returns in bitcoin. As an alternative, MinerWorld offered to pay investors immediately in Mcash, a newly created altcoin that has no market value. The token cannot be traded on public exchanges and exists only within MinerWorld's internal "M360 exchange"—essentially trapping any investor who accepts it.
The scheme exemplifies how cryptocurrency platforms exploit regulatory gaps and investor inexperience. By offering impossible returns and burying payment obligations under technological jargon, MinerWorld collected millions before authorities intervened. The company's willingness to offer worthless tokens as repayment shows organizers had no intention of honoring their commitments.
For the thousands of Brazilians who invested in MinerWorld, recovery remains uncertain. The frozen assets may eventually be returned through legal proceedings, but only after lengthy court battles. Those who accept Mcash payments will almost certainly lose everything.
