Lin and other three "post-95" guys engaged in the "business" of buying and selling foreign exchange through the medium of virtual currency transactions. In just a few months, they completed more than 650 transactions and exchanged foreign exchange for nearly 30 million yuan. The Jianhu County Procuratorate filed a public prosecution, and the prosecutor reviewed that the three provided cross-border exchange and payment services through the medium of virtual currency to earn exchange rate differences. They used the special properties of virtual currency to bypass the national foreign exchange supervision, affect the effectiveness of foreign exchange management and the stability of the legal exchange rate, and disrupted the normal financial marekt order. They should be investigated for criminal responsibility for the crime of illegal operation according to law. Lin and other three people were sentenced to five years in prison to one year and six months by the court for the crime of illegal operation, and each was fined.
