Bitcoin's computing power is concentrated in China
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
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
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm.

according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk
warm tips: the above information is for reference only. Before investing, it is recommended that you first understand the risks existing in the project, and understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

Although many countries do not recognize the value and status of bitcoin, bitcoin is still popular in recent years, and its existence is controversial. Some people say that it has no practical significance, just a number. If it is not officially recognized by the world, mining is a constant waste of energy. Some people say & lt; No one can be sure whether bitcoin is a black horse or not
in fact, bitcoin is calculated and proced through computer networking, also known as mining. At the beginning, there was a personal computer to dig, but the efficiency was relatively low, and the cost of graphics card was low. Then there was a special bitcoin mining machine, ranging from several hundred to two or three hundred thousand yuan
when we talk about bitcoin, we naturally need blockchain because of the blockchain, bitcoin can become bitcoin. It is a secure general ledger for all payments and transactions. It can be said that everyone can contribute to the update. We need to solve a very complex mathematical problem by brute force& mdash; Hash algorithm to complete a block
many people want to know the value of a bitcoin. In fact, the price of bitcoin is changing all the time. We need to check the figures of that day. At present, the price of a bitcoin is less than 30000
as for whether bitcoin can develop in China, it depends on whether foreign bitcoin can develop better. If foreign bitcoin can continue to exist and develop rapidly, then bitcoin will usher in the second spring in China. Chinese style is a conservative country, China likes to use the doctrine, does not like to innovate
I believe that bitcoin is a better means of payment and may become a supplement to the existing currency
of course, the growing popularity of the mining instry has also boosted the soaring price of bitcoin to a certain extent. From Avalon 1 to Avalon 3, and the emergence of other ASIC mining machines, the computing power of the whole network has been continuously boosted. It is said that Avalon's 28nm and 16nm chips will also be put into the market in the future, when mining will be more difficult, The price of bitcoin is also expected to rise.
it's not as safe as gold
1Ghash=1,000 M hash
at present, bitcoin mining is a very professional business, and the computing power is mainly concentrated in several big miners. At present, more than 60% of bitcoin computing power in the whole network is concentrated in China, and China has a certain say in bitcoin, but the core R & D and maintenance team of bitcoin is still abroad
digital currencies similar to bitcoin include Leyte coin, Ruitai coin, Ruibo coin, doggy coin, thousand gold card, etc.
