Virtual currency full position
the first category is familiar game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the first two types can be regarded as one, which is only a detailed difference in function. Since the end of 2016, the third type of digital currency has quietly entered our life, which refers to the digitization of currency. Digitization doesn't mean scanning. This is just like digital signature. Digital signature does not mean scanning your signature into a digital image, or using the touchpad to obtain the signature, let alone your signature. Digital currency is often mistaken for virtual currency. But virtual currency refers to non real currency. For example, when you play "Three Kingdoms" (game) or "grand Voyage", you have money, which is virtual, that is, the first and second categories we just described. Of course, the virtual money will also have its real value. For example, if you buy her / his account from another player, you can get all the virtual assets of that player, and then it will be much easier for you to continue playing. Virtual money is not necessarily digital. For example, children play games with pebbles as virtual currency
there are also obvious differences between the transaction rules of digital currency and virtual currency. In most cases, the value of digital currency is higher than that of virtual currency, and it needs more strict transaction rules to carry out transactions
the top three currencies of digital currency are BTC eth EOS
Because now people are influenced by some comments on the Internet, such as bitcoin, its value has increased many times since it came into being, people think that virtual currency should be a very promising thing, so many people follow suit
if you really have a lot of spare money, you can consider investing in some stable bonds, some science and technology innovation board and stocks, but don't invest too much in virtual currency strong>
