Daily transaction scale of bitcoin
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million
extended data
monetary characteristics
1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
2. Global circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3. Exclusive ownership: private key is needed to control bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
4. Low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
5, no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6. Cross platform mining: users can explore the computing power of different hardware on many platforms
Let's start with a simple conclusion: a year ago, the data showed that there were about 500000 BTC
two American brothers, Cameron winkleworth and Taylor winkleworth, claiming that they owned 1% of bitcoin [1] 1% of the world's bitcoin? At present, the total amount of bitcoin in the world is about 12 million, that is to say, the two brothers hold about 120000 bitcoins< maybe you don't think it's worth much, but note that the starting price of bitcoin for these two people is less than $10 / bitcoin
Please note that entities are used instead of people. In the analysis method of this paper, bitcoin wallets that may belong to the same owner are divided into the same entity, which may be not only a person, but also a trading organization like Mt. GOx in addition, through the analysis of the most active entity table given in this paper, the income of the people with the most income (excluding expenses) is less than 700000 BTC. In other words, the person with the most bitcoin will hold no more than 700000 bitcoins. How many people in the world own bitcoins? The paper concludes that as of May 13, 2012, 1.85 million entities hold bitcoin. If we assume that bitcoin users have grown linearly since the advent of bitcoin (January 2009), the current number should be 2.5 million. Because the number of entities is counted on paper, the actual number of bitcoin holders should be a little less than this number, but not much smaller, because after all, there are not many large trading platforms
In addition to the above two problems, [3] also gives many interesting conclusions, such as: < UL >about 55% of bitcoin can be saved without money
in places like GOx mountain, almost all deals are small ones
before May 2012, almost all large single transactions (& gt; 50000 BTC) are subsequent transactions of 90000 BTC on November 8, 2011. There are very strange patterns in this long list of transactions. For example, an entity divides 90000 BTCs into different sizes, sends them back to itself three times, and then sells them on Mt. GOx. 90000 BTCs sold are sent back to the entity through 90 different bitcoin addresses, with 1000 bitcoins per address. These operations indicate that the entity appears to be trying to hide the relationship between these transactions
bitcoin is also proced by mining. Mining is the process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary
however, at present, the profit margin of mining is very small, and the mining cost has approached or even exceeded the currency price. Now mining is mainly about electricity price and energy consumption. Of course, it also needs the support of faith. Go to bitcoin home to learn some basic bitcoin knowledge, so as not to be cheated.
there are plenty of investment procts. Why is bitcoin so valuable? This should consider not only the nature of bitcoin itself, but also the process of history. Bitcoin's own nature is concive to value-added, and history has indeed come to the process of increasing the price of bitcoin< In recent years, the pressure of economic downturn has been great, and the global economy has slowed down significantly. In this case, people tend to buy investment goods with value preservation, rather than invest money in consumer goods or proction. Bitcoin is a good place to invest
as mentioned earlier, the number of bitcoin is constant and it is not controlled by the central organization, which means that bitcoin has good reliability. In addition, bitcoin can be invested through the Internet, while the traditional investment threshold is relatively high, so the speed of capital entering bitcoin is particularly fast. The price of bitcoin has been unstable, which is also related to the fast in and fast out nature of the Internet. And the current economic situation is promoting the rapid flow of capital into bitcoin< Foreign exchange control
e to the great downward pressure of economy, in order to prevent capital outflow and ensure the stability of exchange rate, all countries have adopted a certain degree of foreign exchange control measures. For example, China has adopted relatively strict RMB exchange control. If you want to exchange RMB into US dollars, there are many restrictions. Ordinary people can only exchange US $50000 a year. At this time, bitcoin has become a means to circumvent foreign exchange restrictions
for example, you can use RMB to buy bitcoin and exchange bitcoin for us dollars. You can exchange through different trading platforms. For example, you can buy bitcoin in RMB on Chinese websites, and then sell bitcoin into US dollars on American websites. As a result, bitcoin has been welcomed by many money launderers, and its price has gone up all the way<
the regulation of bitcoin trading platform is relaxed
it is difficult to monitor the transactions between bitcoins, but the bitcoin trading platform can be monitored. For example, if your trading platform is a Chinese website, it will naturally be regulated by the Chinese side. At the beginning of this year, e to the intervention of regulatory authorities, three domestic bitcoin trading platforms suspended the withdrawal of bitcoin, and bitcoin fell sharply. However, in June, these bitcoin trading platforms resumed the withdrawal service, claiming that they had completed the upgrade of the anti money laundering system. This is good news for bitcoin, and the rise of bitcoin price is reasonable< Influence of bitcoin blackmail virus
the recent bitcoin blackmail virus wannacry is impressive. Wannacry encrypts computer data and blackmails users to pay for bitcoin decryption. The virus is spreading everywhere, and many people are forced to buy bitcoin to redeem the data (but the data can't be decrypted), which also pushes up the price of bitcoin
we can see that there are many factors driving up the price of bitcoin. In fact, in addition to bitcoin, the prices of other similar digital currencies are soaring. Bitcoin is generated based on algorithms, and other digital currencies with similar principles include lightcoin, Ethereum, dogcoin, etc. The price of these digital currencies, especially Ethereum, has also risen significantly recently. Ethereum and other coins are still profitable even if they use graphics cards for mining. Recently, amd graphics cards are out of stock, and the culprit is Ethereum and other coins. For this reason, AMD and NV intend to launch mining special supply cards to avoid mining affecting the normal sales of graphics cards
summary
although the price of bitcoin is rising faster than that of a house, this investment is still full of risks. The price of bitcoin fluctuates very violently. For example, in 2014-15, bitcoin even fell by nearly 90%. This "mining disaster" also made many mined graphics cards (mine cards) flow into the second-hand market. Mine card life is often worrying, we need to pay special attention when buying. At present, the rising trend of bitcoin price continues. Will there be a mine disaster next? When is the graphics card not out of stock? Let's stay focused.
