Bid farewell to bitcoin exchange

1. According to incomplete statistics, there are 166 concepts of
bitcoin, which was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software is designed and released, and P2P network is built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency 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 monetary 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.

3. The nodes of bitcoin are software running on the computers of millions of bitcoin users, and millions of bitcoin nodes are interconnected to form a bitcoin network. Bitcoin node software usually includes the following functions:
1) wallet. It's used to store your bitcoin balance. In principle, as long as you have the private key of your own bitcoin address, you can use your own bitcoin
2) verify the transaction or payment. After receiving the transaction, the bitcoin node will use certain algorithms to verify the validity of a transaction. If you only change the balance of bitcoin in your computer, others will not recognize it. Similarly, your wallet will not recognize the transaction changed by others
3) mining. Core wallet can start mining function through a command to join the mining army, while SPV wallet usually can't (SPV is just passing by). However, it is not the node type that hinders home computer mining, but the rapid development of professional mining machines. Compared with ordinary computers, the computing power of ordinary computers is very small. Mining by ordinary computers is like digging your own backyard with a hoe, and then expecting to dig out gold
because of the demand of bitcoin users, bitcoin exchange was born. The exchange provides a place for centralized trading. People put money on the exchange, and the exchange will match and trade together, similar to stocks and securities. Therefore, banning exchanges does not mean banning bitcoin. Bitcoin network cannot be banned. Bitcoin is sent to the exchange's wallet, and all you see is a balance given to you by the exchange. In fact, you no longer have your own bitcoin. Bitcoin network is global. Where there is a network, there will be bitcoin. After the exchange closes, bitcoin will not disappear, but will return to where it should be.

4.

The well-known ones must be the heads of those major exchanges. You can download them and experience them. You can see which one is most suitable for you. The experience of each exchange is different. Only after the experience can you know who is better. Indivials use the whale exchange. The heads of major exchanges are as follows:

centralized trading platform

5.

On the evening of September 14, bitcoin China's official website announced that according to the spirit of the document issued on September 4, bitcoin China digital asset trading platform stopped new user registration from September 14; On September 30, the digital asset trading platform will stop all trading business

except bitcoin China, the other two platforms have not released relevant announcements yet. In response to reporters, Huo coin said that it has not received any clear documents or notices about the content of news reports. Okcoin said that the official announcement of okcoin should be taken as the standard

virtual currency has a long way to go and needs further supervision

6. In the coin egg, select "C2C", recharge to buy USC, then select "USC area" on the home page, select "USC / BTC", and trade bitcoin.

7. If you buy it on a regular platform, even if the exchange goes bankrupt, bitcoin will still be there, except that you can take it away before the exchange goes bankrupt; But if you buy it on an informal platform, you may not be buying BTC at all. It's very likely that it's a bunch of numbers, so it doesn't matter whether you're here or not.

8. 1. The law of multiplication is extended to fractions
the law of integer multiplication is extended to fractions, so that students can feel the subtle relationship between the multiplication of fractions by integers and the addition of fractions with the same denominator

2. Remember the pithy formula well
brackets should be calculated first with brackets, from front to back without brackets, multiplication and division first, and then addition and subtraction

3 Clear the concept
let students understand that the reciprocal of an integer is one of the original fractions, and the reciprocal of a fraction is to exchange the numerator and denominator

9. Generally, you click the minus sign in the transfer out platform, and then click the plus sign in the transfer in platform. There will be a string of letters representing the address. Copy the address to the platform you want to transfer out. And then a little bit of certainty turned out
thank you
