NEW YORK, June 27 (Reuters) - A Florida man was sentenced on Tuesday to serve 5-1/2 years in prison after pleading guilty to operating an illegal bitcoin exchange suspected of laundering money for hackers and linked to a data breach at JPMorgan Chase & Co.
Anthony Murgio, 33, of Tampa, pleaded guilty on Jan. 9 to three conspiracy counts, including bank fraud and operating an unlicensed money transmitting business. The sentence was roughly half as long as prosecutors sought.
Murgio and co-conspirators were accused of having processed millions of dollars from 2013 to 2015 into the virtual currency bitcoin through the unlicensed exchange Coin.mx.
Prosecutors said many transactions were conducted by victims of ransomware, a malicious software that locks up data unless people pay "ransom" to unlock it. Cybercriminals often demand ransom paid in bitcoin.
The alleged schemes also involved the takeover of a New Jersey credit union to shield their activity. The credit union was later liquidated.
"Mr. Murgio led an effort based on ambition and greed," and constructed on a "pyramid of lies," U.S. District Judge Alison Nathan in Manhattan said during the sentencing hearing.
Nathan imposed a sentence shorter than the 10 to 12-1/2 years recommended by prosecutors and federal guidelines, citing Murgio's generosity to friends and support to his family.
Murgio unsuccessfully fought back tears and lost his composure several times in expressing "enormous regret" for his crimes, which the judge credited as genuine.
"I am wiser today than when the case began, and I am sorry for all the damage I caused to so many people," Murgio said. "Believing what I was doing was okay did not make it okay."
Murgio's lawyer Brian Klein emphasized how his client had taken responsibility for his "grievous decisionmaking."
In contrast, Assistant U.S. Attorney Eun Choi pointed to the ransomware victims in seeking a stiffer sentence.
"He exploited their desperation to personally profit from them," she said.
Murgio's father, Michael, pleaded guilty last October to an obstruction charge tied to the credit union.
Anthony Murgio was one of nine people criminally charged following an investigation into the JPMorgan breach, which exposed more than 83 million accounts.
Prosecutors said Coin.mx was owned by Gery Shalon, who was extradited last June from Israel to face U.S. charges. He has pleaded not guilty.
In March, a Manhattan jury convicted Florida software engineer Yuri Lebedev and New Jersey pastor Trevon Gross of scheming to help Coin.mx conceal its activities from banks and regulators. They have yet to be sentenced.
