ZeekRewards — $850 Million

ZeekRewards defrauded nearly one million victims of $850 million—at rank 8, it rivals #7 OneCoin's $4 billion in victim count, though at a smaller dollar amount. The penny auction site promised 1.5% daily returns for posting fake ads, which amounts to an annualized 547% gain, unsustainable after 60 days. The SEC's shutdown in 2012 revealed that less than 10% of assets were real. This scale outpaces the average Internet Ponzi: Zeek's $850 million is 85 times larger than the typical affiliate scam. Victims lost an average of $850 each, with some losing $50,000.
