Current BTC global computing power
The following is the distribution chart of computing power:
the computing power of bitcoin is mainly controlled by some mine owners in the world, and the computing power of retail investors is very small, almost negligible. The computing power of China's mining pool even accounts for more than 80%, and China's voice is increasing
however, many digital currencies no longer need to be mined. Some digital currencies will be directly sent to investors through ICO, and Puyin is one of the representatives, but these digital currencies generally correspond to real assets
Bitcoin bulls often mention that the scarcity value of this cryptocurrency is the main reason for its continued rise. Bitcoin is similar to gold to some extent. The growth of its supply is extremely slow, and it is still slowing down. Its total supply will only reach 21 million
with the increasing interest of institutional investors and retail investors in bitcoin, global exchanges such as the Chicago Board of options (CBOE) have launched bitcoin futures contracts. This is likely to encourage more institutional investors to invest in bitcoin, while at the same time further curbing the price volatility of bitcoin
this much anticipated bitcoin futures trading has been launched on the Chicago Board of options exchange, which represents a significant step in the legalization of cryptocurrency. Futures is a derivative / financial instrument, which can force dealers to buy and sell an asset at a specific time and price
There are only 21 million bitcoins
"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations
{rrrrrrr}
extended materials:
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. 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 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. 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
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
on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees
BTC means bitcoin
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p
No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law
extended information:
{rrrrrrr}
transaction mode
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
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. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions
At present, bitcoin needs to be g by professional mining machines. The global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
according to the current speed and the number of bitcoins, it will take three months to get a bitcoin if a computer is kept in a 24-hour state of operation
extended data:
because the current bitcoin mines use special bitcoin mining machines to mine. The computing power of an ant S9 miner is 13.5th/s, which is equivalent to the sum of the computing power of 7500 1080ti graphics cards. A medium-sized mine has hundreds of such miners
the instry of bitcoin is not very good either, so you'd better not dream of becoming rich overnight with bitcoin. Now many countries have issued policies to suppress the rise of bitcoin prices. Some countries even refuse to dig bitcoin. Many bankers and economists are disgusted with the emergence of bitcoin
