Bitcoin shopping
this kind of digital currency, represented by bitcoin, is very controversial now. Although there is speculation in China, the number is very small. If you haven't touched this kind of digital currency before, I suggest you don't touch it. It won't make you rich overnight, on the contrary, it will make you bankrupt
after the popularity of bitcoin, there have been many similar digital coins in China. Now most of them have become air coins, half of them have returned to zero, and few of them have become pyramid selling coins and continue to harm people
therefore, it is not recommended to invest in bitcoin, remember!
the second way of transaction is completely private transaction. First, the two sides of the transaction contact each other, and then the seller in the trader transfers the virtual currency such as bitcoin to the buyer's wallet directly through the wallet such as bitcoin. At the same time, the buyer gives the seller the money needed by the exchange or other virtual currency of equal value. Here, the price traders can communicate with themselves, which saves the trouble of platform registration
compared with the two methods, the trading platform needs to be registered and the real name system is adopted. For users who are afraid of trouble and unwilling to trade in real name, they are more inclined to choose private trading. Moreover, the service charge required by the platform exchange is actually very high. These are the factors that some people choose to trade in private. However, private transactions also have many disadvantages. One is the uncertainty of the transaction. If the two parties do not meet for the transaction, there may be the risk that one party will pay and the other party will run away. Even if they meet and trade, there may be something similar to stealing bitcoin directly or transferring bitcoin into their own hands through threats. Another is that the liquidity is not strong, and it is not necessarily possible to find a private trading partner at any time. However, private transactions sometimes appear in the hands of large investors, and millions of transactions may be directly traded in private. At this time, transactions may be based on long-term cooperation and trust
I used to make bitcoin, and I lost half of it at once. It's not online or offline, and the risk is very high. It's better not to touch virtual currency, which is not recognized by China
mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao
3. Reward for bitcoin
with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security
in fact, Mr. Xiao Zaojun paid attention to this very early. Last year, I wrote a popular science article about blockchain and bitcoin. At that time, the price of bitcoin seemed to be $3000, and many people suggested that I start. After thinking about it, I still didn't buy it
later, bitcoin soared and plummeted, peaking at $20000, and then quickly fell to $8000. I'm both sorry and glad<
today, I've also rerouted that article (with some revisions). I hope it will help you to know more about blockchain and bitcoin technology
in my opinion, whether you invest in bitcoin or not, whether you believe in blockchain or not, first of all, you should fully understand them

The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees. Is bitcoin a currency? Bitcoin is an "e-coin" proced by open source P2P software
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
another advantage of bitcoin is decentralization and privacy protection. At the beginning of the design, the technology regarded the government as the enemy, and wanted to decentralize the monetary power and not be influenced by the government's monetary policy. Nakamoto, the founder, is an anarchist himself and thinks that the government will persecute the people
bitcoin is more like a stock, like the stock of a payment company. What is bitcoin: 1. A currency? 2. A payment method? 3. An asset type? 4. A gambler
recently, bitcoin platform has been shut down by China, and bitcoin is the only e-currency conforming to Utopia. Bitcoin, which relies on proceres and encryption, exists in mathematics. It relies on the super computing power of the whole world to ensure transaction nature. It relies on the market to realize self value, and the quantity of issuance is limited. It is the real currency, the truth, and bitcoin may also be a bubble. Some people say that bitcoin is another Ponzi scheme
bitcoin is an experimental tool only belonging to the top IQ group to test their own theories; But now it has become the weapon of the mob. If we regard bitcoin as a decentralized currency experiment, bitcoin ecology is falling into a whirlpool of accelerating centralization: short-term arbitragers become the main force of its transactions, and the application scenario of bitcoin as a payment method seems to have come to an end, leaving only the property of speculation / investment goods
Bitcoin is a quadruple network effect. Including: 1. Consumers who pay with bitcoin; 2. Businesses that accept bitcoin; 3. The miner who proces and confirms the effectiveness of the transaction; 4. Entrepreneurs and programmers who develop new procts and services around bitcoin. The fourth group is particularly critical to the future of bitcoin
