On April 9th, a 33-year-old Danish man was sentenced to four years and three months in prison for spending more than $450,000 on bitcoin (BTC). According to reports, the man used bitcoin for money laundering and sent the money to his associates through an unspecified foreign cryptocurrency exchange account. Local police said the authorities were fully capable of cracking down on illegal activities related to the encryption industry. National regulators are increasingly concerned about the illegal use of cryptocurrencies. For example, the G20 Group will hold a meeting in Fukuoka, Japan in June to discuss anti-money laundering and counter-terrorism financing regulations in the field of encryption.
