Nov. 21 (UPI) -- Two Estonian citizens were arrested on Sunday after allegedly defrauding hundreds of thousands of people in a cryptocurrency scheme.

The Justice Department unsealed indictments for Sergei Potapenko and Ivan Turõgin, both 37, for luring victims into paying more than $575 million through an elaborate plan involving bogus rental contracts, cryptocurrency mining and a fake bank.

The duo allegedly tricked victims into entering equipment rental contracts in their cryptocurrency mining service HashFlare. They also convinced victims to invest in Polybius Bank, which was not an actual bank. They then used a series of shell companies to launder the fraudulently acquired money.

"New technology has made it easier for bad actors to take advantage of innocent victims -- both in the U.S. and abroad -- in increasingly complex scams," said Assistant Attorney General Kenneth A. Polite Jr.
