IRS-CI Special Agent in Charge Thomas Fattorusso said: “$2 billion in transactions with an unlicensed money transmitter means $2 billion flowed without any oversight, from whomever to wherever. Because of the company’s disregard for regulation, it’s alleged that Samourai Wallet laundered more than $100 million in criminal proceeds
Transactions are not unlawful cause you cannot trace the flow of the transaction. The $2 bliiion seems to have just been thrown in there for shock value, giving them a justification to clamp down on the service.
Cash pretty much allows anyone to transact without regulation or oversight, and way more than $100 million have been used in criminal transactions using it.
