Federal authorities arrested an Ohio man for operating a cryptocurrency laundering service that moved some $300 million in bitcoin via a “tumbling” operation. Larry Dean Harmon of Akron ran an operation called Helix, which partnered with now-defunct underground marketplace AlphaBay, known for illegal activity including drug deals, according to the Department of Justice. The feds shut down AlphaBay in 2017.
"Cryptocurrencies have become an asset class worth hundreds of billions of dollars, yet regulatory oversight remains fragmented and undeveloped. For all the promise of the blockchain, bitcoin and initial coin offerings, there’s also plenty of hype, fraud and criminal activity," the full proposal said.
