Can bitcoin buy and sell real things

1.

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

extended data

users can buy bitcoin, and at the same time, they can "mine" bitcoin by using computers to perform a large number of calculations according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

from 2012 to 2014, bitcoin swept the world, and graally formed the "virtual currency" instry chain represented by bitcoin. This is a change in the financial instry and a new proct of the combination of the financial instry and the Internet. It represents a financial milestone in the new era and marks a new chapter in the history of the Internet. Bitcoin fund is one of the derivative procts represented by bitcoin in the era of "virtual currency"

according to the relevant news reports of Fuhui China, bitcoin fund will be open for operation in the autumn of 2014. Fuhui bitcoin fund, as the world's first operation mode of mutual benefit and win-win with financial management mode, is original and full of temptation and challenge

2. The first, the most common and the most popular way for bitcoin participants to choose, is to choose a trading platform. Now the trading platform, with the strengthening of supervision, all need the real name system. Generally speaking, it's better to choose a larger and influential trading platform. On the one hand, it's more secure and reliable. On the other hand, it's more currency, active trading and good liquidity. When the platform is selected, the first step is to register. Generally speaking, it needs telephone registration or email registration. After registration, it requires the real name system. The ID card and the corresponding bank card go to the real name system. This is just the general real name system. If there is no real name system, most platforms are restricted from trading. In the general real name system, there are also restrictions on the amount of money, and there are restrictions on the daily withdrawal of money or cash. If you want to improve the amount of money, you need advanced authentication. Advanced authentication generally requires video authentication, handheld ID card, etc. After the end of advanced authentication, the permissions will be much better. At this time, you can exchange legal currency and virtual currency with other traders through legal currency trading in the platform. At present, domestic platforms do not provide direct recharging of legal currency, but provide mutual exchange of legal currency and bitcoin among different traders to achieve the goal of recharging. This is the C2C end of the transaction, the platform is only to provide security and exchange channels. Through C2C terminal transactions, legal currency can be changed into different virtual currencies in personal accounts. However, there are not many kinds of virtual currencies that can be changed, such as bitcoin. With these currencies, you can buy and sell multiple currencies through currency transactions on the platform. This kind of trade way is the trade way that most players choose
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

3. 1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
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

next, brush the map, brush the good stuff in the awesome prize pool, and the garbage will be brushed together.
thirdly, the novice should wear all the titles
finally, draw a lottery at the right time. The right time is king. Generally speaking, there is a higher probability of good things coming out at 20-23 o'clock. You can observe for a few more days and watch the time to find the right lucky draw.
