This is not clear, it should be a certain agreement. However, the cooperation between virtual money funds and companies is mostly to achieve some kind of profit.

Network virtual currency can be roughly divided into

The first category is the familiar game currency. In the era of stand-alone games, the protagonist accumulated money by knocking down enemies and winning money in casinos, and used it to buy herbs and equipment, but only in his own game machine. At that time, there was no "market" between players. Since the Internet established portals and communities and realized the networking of games, there was a "financial market" of virtual currency, and players could trade game coins.

The second category is the special currency issued by portal websites or instant messaging service providers to purchase services within this website. Tencent is the most widely used QQ coin, which can be used to buy value-added services such as membership and QQ show.

The third virtual currency on the Internet, such as Bitcoin (BTC), Litecoin (LTC) and Fortune Coin (FTC). Bitcoin is an electronic currency generated by open source P2P software. Some people translate it as "Bitkin", which is a kind of online virtual currency. It is mainly used for internet financial investment, and can also be directly used as a new currency in life.
