Once the Libra system is established, it can bring new subversive possibilities at any time. What is the possibility? The answer is to change the runway from financial runway to retail runway. Facebook has 2.7 billion users, and the payment channel is opened. Instead of issuing money with financial logic, Facebook can wholesale the right to take delivery of goods of multinational companies with the logic of collective purchasing. It doesn't matter whether this right is called Libra or not

3. Once the infrastructure is built, Facebook can change a runway to issue money at any time, which is the simplest wholesale logic. It is the logic that consumers buy bus cards. But once this simple logic is completed in a network, the actual result is the issuance of currency

4. The value that Facebook can bring to the society after changing the track: all the new Libra are profits for the whole market. This profit is shared by Facebook users, Facebook and Facebook partners, which will stimulate the capital action of the whole market and create more Libra and profits. It's too late for other competitors to follow up, because the funds are synchronized in the cloud. Therefore, if Libra succeeds, it will be a stronger new dollar, a new currency that can subvert the financial system of all countries

5. The bank system manages account numbers. Facebook, too. Other Internet platforms are the same

but after the sharp rise of bitcoin in 2017, more and more people began to pay attention to cryptocurrency, understand cryptocurrency, invest in cryptocurrency, and long for cryptocurrency to bring rich economic returns. However, after several in-depth studies, bitcoin is the only cryptocurrency with value and significance. The reasons are as follows:

the total supply of bitcoin is constant. As time goes on, bitcoin will become more and more rare and become a very good means of value storage, similar to gold. In the past 10 years, this function of bitcoin has become a consensus

bitcoin is the leader in cryptocurrency, which is an absolute consensus in this instry. Looking back over the past few years, among the top ten cryptocurrencies in terms of market value, only bitcoin has always been the first, and the remaining counterfeit currencies are all in the past
