Whether in the past or in the future, we have always advocated that indivial interests should be in line with collective interests. When facing social and economic interests, we should first consider social value. When dealing with virtual currency shuttling through financial transactions, how should we choose its social and economic value
there are thousands of virtual currencies in circulation in the market, and not every currency will follow the principle of social value first. From December 17 to January 18, many virtual currencies scrambled the trading market by virtue of ICO chaos, which not only made many investors lose money, but also lost the hope of increasing the value of virtual currency, This kind of virtual currency not only has no social value, but also can never realize its own economic value
As the first virtual currency to appear in the public's eyes, bitcoin is a financial proct with both social and economic values. It not only grows graally in the process of development, from less than $1 to $10000 + today, but also drives the development of the whole instry. Bitcoin is the leader and protector of the emerging instry, Its contribution is multifaceted and its advantages are incomparable As a new emerging virtual currency, mycoin may not seem warm now, but the soup made by slow fire is often different. I hope mycoin will move closer and closer to bitcoin and compete with it in the near futuretrading platform launched on June 9, 2011

bitcoin is a new type of virtual currency, which is generated by a large number of calculations based on special algorithms. According to rigorous calculations, the stock of bitcoin is limited, with a total of 21 million, no more or less. After being created, bitcoin has rapidly become a "fixed asset" pursued by Internet speculators
in February 2014, mtgox, the world's largest trading platform, went bankrupt, casting a shadow on the whole bitcoin instry. Since the middle of 2014, the price of bitcoin has been in a downward trend for a long time

When bitcoin first appeared in 2009, its price was less than 1 cent. One dollar could be converted into 1300 bitcoins, that is to say, seven yuan could be converted into 1300 bitcoins. On May 5, 2017, bitfinex, an overseas digital currency trading platform, quoted a price. Bitcoin once hit US $1700, or about RMB 11737
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
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 feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. 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
extended data:
transaction method
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 doesn't need to exchange information online, so it can be offline. There are a lot of bitcoin addresses available
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 is used to record how much bitcoin is stored in the address. You can generate bitcoin address to store bitcoin at will. When each bitcoin address is generated, a corresponding private key of the address will be generated
this private key can prove ownership of the bitcoin at the address. The bitcoin address can be simply understood as the bank card number, and the private key of the address can be understood 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 the address and private key when using bitcoin wallet

Bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

Bitcoin network generates a new block every ten minutes. Every time a miner completes a block, he can get a certain amount of bitcoin as a block reward, and the reward will be halved for every 210000 blocks mined. Because the time for mining each block is limited to 10 minutes, at this rate, the period for the reward to be halved is four years, that is to say, the reward for bitcoin blocks is halved every four years
when the bitcoin block reward was halved for the first time, its price rose 25 times from 300 yuan to 7995 yuan; In the second half, the price rose 28 times from 5011 yuan to 140000 yuan. So many people predict that the third halving of bitcoin in May 2020 will lead to a sharp rise in the price of bitcoin, at least 10 times. However, these figures are not so clear. After halving in 2012, bitcoin prices rose for two months, and in 2016, there was almost no immediate response to deflation for a month. This may also be the result of the strategy of "buying rumors and selling news" implemented by some speculators
extended data:
after bitcoin halved, the supply slowed down, and keeping deflation through algorithm has always been a part of bitcoin protocol design. It was set up to ensure the value of bitcoin. By recing block incentives and setting the maximum possible supply of bitcoin at 21 million bitcoins, bitcoin has an anti inflation feature, which runs counter to the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation, and less than 3.5 million bitcoins are available for mining. When the next block award halves, bitcoin's annual inflation rate will drop from the current 3.8% to about 1.8%
maintaining deflation through algorithms has always been a part of the design of bitcoin protocol. It was created to guarantee the value of bitcoin. By recing block incentives and keeping the total amount of bitcoin at 21 million bitcoins, bitcoin is endowed with an anti inflation nature, which is different from the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation and less than 3.5 million available for mining. The next block award cut in half could rece bitcoin's annual inflation rate from the current 3.8% to about 1.8%. This will be the first time in bitcoin's history that it has fallen below the historical average of about 2% - 3% growth in gold supply
bitcoin is actually an e-coin data coin proced by P2P batch software, which belongs to a network virtual asset so bitcoin is also called bitcoin. It is generated by a set of cipher codes through complex algorithms. This rule is not interfered by any person or organization. Anyone can download, run or participate in the manufacture of bitcoin. One of the biggest characteristics of bitcoin is that it cannot be forged< you can make money in the bitcoin market by investing time and money
when you spend time on websites, you can visit these websites every few minutes to get a small amount of bitcoin. Therefore, we can do this if we have time. If you want to earn more, you should invest money in the early stage. Bitcoin also has a special casino, so you can earn more by luck
