OneCoin alone is over $4 Billion Dollars, but I believe it is closer to $7 Billion Dollars and they are still signing people up. Consider there were over 130 new fake crypto-currency MLM programs launched from March 1 through September 30 in 2018. When you add in all the theft of real crypto-currencies by hackers of major storage houses, I can see it reaching $1.7 Billion. The theft from Mt. Gox alone was in the hundreds of millions of dollars.
