Buy and sell bitcoin
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
The remitter will pay bitcoin directly to the other party according to the address of the payee through the computer or smart phone
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed
the bitcoin peer-to-peer network stores all transaction history in the "blockchain". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. In fact, blockchain is a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history

special attention:
1. When purchasing and selling bitcoin, it is necessary to deal with it in time, and do not need card orders. For example, after placing an order, you need to pay in time and click paid. After others pay you, you need to put money in time. Otherwise, the other party will appeal to Huo coin
2. The collection account must be filled correctly
3. The risk of currency market is high and investment should be cautious
after buying bitcoin, if you want to change it into other currencies, such as EOS and Ethereum, you can go to the currency trading platform and directly click the hanging order to sell it and change it into other currencies you want. If you want to change money, you can sell it on the off-site platform. People who need to buy will contact you, operate on the platform, and then pay offline< strong>

2. Unlike all 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 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 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

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
1. The withdrawer is a registered user of a bitcoin trading platform
the user can enter the background of the trading platform and withdraw at any time; The security of cash withdrawal is guaranteed by the platform itself
2. Bitcoin wallet
the withdrawer is a registered user of a bitcoin wallet. The user can enter the background of bitcoin wallet to provide operation, and the security is provided by the wallet platform. The coin bag is similar in nature
3. Private transactions
the withdrawer can cash his personal bitcoin by concting private transactions with others (with bitcoin demand)
this is also a channel for bitcoin cash withdrawal, but there are certain risks in similar transactions.
