What does bitcoin invest in

1. First of all, you need to know what bitcoin is and whether it has a future. This is the biggest factor for you to decide whether to invest or not. Do not follow suit. Bitcoin is the first distributed virtual currency. The whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom. Bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin. If you want to trade, choose a professional platform. Now I do it on ZB. After a series of operations such as registration, real name binding and so on, I can start trading.

2. In fact, there is no very accurate definition of microservice architecture, which roughly describes a large complex software application system composed of several microservices. Each microservice in the system can be deployed and expanded independently, and each microservice can provide a stable mole boundary. Each micro service is loosely coupled, micro service is very small, focusing on one thing. Microservice framework has good technology heterogeneity, flexibility and scalability. Its simplified deployment provides a huge impetus for continuous delivery. But it also brings some challenges, such as distributed transaction consistency, network performance consumption and so on. Therefore, the selection should be combined with the actual business considerations. If you want to further study, it is recommended to use some ready-made open-source microservice frameworks of some large manufacturers to develop a trial hand. You can use spring cloud and servicecomb. There are a lot of online materials. I hope this answer will be helpful to you.

3. According to the specific algorithm, through a large number of calculations, bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The currency system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
the risk is that the future bitcoin will be stopped by the international machine, resulting in abortion

4. Bitcoin is a kind of virtual currency with limited quantity, but it can be used for cash.

5. Guangzhou metro line 17 is planned to be located in the core of the future Guangzhou new town in Panyu District, from west to East, from Zini station through Panyu Square Station to GAC base station. Connecting with line 4, East extension of line 3, line 8, line 18 and line 22, it is an important line to form the core rail transit network of Guangzhou new East in the future
