After the seizure of Mt. Gox’s Dwolla account, the federal government continues to pressure those who exchange and use virtual currencies, especially when the anonymity allows for money laundering. Today, the government announced arrests and seizures of Liberty Reserve, a company that provided transfer and exchange service of virtual currencies, including Bitcoin. News agencies describe Liberty Reserve as a favorite of cybercriminals due to lax anti-money laundering recordkeeping for customers.
