Learn through blockchain from 0 to 1
From 2015 to 2017, the price of bitcoin increased from more than $100 to $17000, a 100 fold increase. Today, the market value of various numerical currencies is more than 700 billion US dollars. The myth of their benefits is not nonsense
but there are many things behind the chaotic digital currency. You may ask why air currency can be listed on the stock exchange? It's very simple. The exchange also has to charge a part of the fee. Raise the price and then sell it to make money. So the question is, how to identify air currency
first of all, you need to look at the projects behind the digital currency and see what their team background is. Generally speaking, teams without experience in the instry tend to earn money, but how much experience do they have? It is better to be able to participate in the construction of Ethereum and bitstock communities. Such a team is often more reliable. This requires investors to have a certain screening ability to identify good or bad
secondly, there is no way to implement many projects. How can we identify them? In addition to the ability of the team, we also need to see the feasibility, which requires us to systematically learn the knowledge of bitcoin and blockchain. For example, Zhu Jiawei, the COO of fire coin network, learned the blockchain from 0 to 1, and clearly described the development process of bitcoin and blockchain in the form of audio and text. Besides, don Tapscott and Alex Tapscott's "blockchain revolution" are worthy of careful taste
moreover, the bubble of digital money is very large nowadays. In the bubble, it is not difficult to make money, but the key is not to be greedy. Long term holding is not good, but it can be operated in a short term. You can make money if you want. However, the key is that people are all profit-making and greed is their nature. Therefore, many people do not accept what they see. They originally made money, but later they lost everything. The gain is not worth the loss. Therefore, it is necessary to control greed
anyone can participate in bitcoin activities, which can be issued through computer computing called mining. The number of bitcoin protocols is capped at 21 million to avoid inflation. Bitcoin is used as a digital signature through the private key, which allows indivials to pay directly to others. It is the same as cash, and does not need to go through third-party institutions such as banks, clearing centers, securities dealers, electronic payment platforms, so as to avoid high fees, cumbersome processes and regulatory problems. Any user can use it as long as he has a digital device that can connect to the Internet
however, e to the limited transaction volume that bitcoin blockchain can accept in a certain period of time, it can accept up to 2500 transactions every 10 minutes, and the transaction handling fee will fluctuate with the transaction volume of bitcoin. In June 2017, the transaction handling fee of less than 1 millibit has been far greater than the transaction amount; In December 2017, steam announced that it would stop accepting bitcoin because of "high transaction costs and high volatility". In February 2018, the average transaction handling charge dropped from $34 in the fourth quarter of 2017 to about $1. This problem is being solved by technologies such as lightning network to expand the transaction volume of bitcoin within a certain period of time
P2P can refer to:
peer-to-peer, a network technology and network topology
file sharing, often using point-to-point technology
point-to-point protocol, which is used for dial-up computing, is usually abbreviated as PPP
Peer-to-Peer Lending, also known as P2P lending, is also known as Internet lending and P2P financing in Chinese mainland.

Many people don't know what blockchain is? But it is the direction of the future. Zhu Jiawei: from 0 to 1, fully understand blockchain
1.0: digital currency decentralization
2.0: smart contract; Digital assets; Financial application
3.0: decentralized mutual trust network; Decentralized trust mechanism
better use of digital currency trading platform "currency exchange"
blockchain 2.0 is a smart contract represented by Ethereum and reborn, or understood as "programmable finance", which is an application to sort out and optimize the use scenarios and processes in the financial field
blockchain 3.0 is the application scenario of blockchain technology in the social field, which extends blockchain technology beyond the financial field and provides decentralized solutions for various instries
1. Open a new word document, click "SmartArt" in the "insert" tab, and select the graphic style to be applied in the "hierarchy" of the selected graphics
2. Fill in the content according to the hierarchy
3. If there are too few graphics in the same hierarchy, you can select a graphic in this layer as shown in the figure below, Add the same level graph
4. Add a subordinate department. After selecting the graph of the Department, add a subordinate department for the Department as shown in the figure
5. If the chairman or the general manager has an assistant, you can select the chairman or the general manager to add an assistant through the steps shown in the figure below. This basically completes an organization chart
6 After the content of the organization chart is completed, we need to optimize the graphical interface. Personally, I prefer to display the organization structure horizontally, as shown in the figure below. You can set it in "page setup". Users can set it according to their own preferences
7. Change the graphics. It is better to use different graphics for different levels. Click to select the graphics to be changed, Select the format to be changed from "change format" under the "format" tab, and then click
8. Modify the layout, click the graphics to modify the layout, and then click "layout" under the "design" tab to modify it to "both"
9. After the layout is modified, if the president's office and other centers are no longer at the same level, You can left click and drag to modify the color of the graph. Under the design tab, click change color, select the color you want to set, and then click
11. After all the settings are completed, a complete organization chart is completed (example graph, for reference only)
