Calculate power, ICO
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
You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on the computer's random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is the so-called proof of work mechanism (POW)
recently, bitcoin's network computing power has entered the era of P computing power (1P = 1024t, 1t = 1024g, 1g = 1024m, 1m = 1024k). In the ever-increasing computing power environment, the arrival of P era means that bitcoin has entered a new stage of arms race
computing power is a measure of the total computing power of the unit that generates new blocks under certain network consumption. The single blockchain of each coin varies with the time required to generate a new transaction block.
Recently, there are three popular concepts: blockchain, bitcoin and ICO
one is the blockchain, which is the blockchain in Xu Xiaoping's internal letter that "if it goes along, it will prosper, if it goes against, it will die"
the other is that it has been hyped for several years, and the price keeps going up and down, but some people have been advocating bitcoin that "each bitcoin will rise to $10000"
Another is the ICO, which Xue Manzi cheered and advocated a few months ago and later was strongly concerned by the regulatory authorities. On the night of January 12, the day before yesterday, the China Internet Finance Association issued an announcement entitled "risk tips on preventing disguised ICO activities", in which it named the digital currency "chain gram" (formerly "play guest currency") released by Xunlei, saying that it "replaces the legal currency payment obligation for the services contributed by the participants, which is essentially a financing behavior and a disguised ICO". As soon as the news came out, Xunlei's share price fell sharply in the early trading of us time on Friday
"bitcoin" does not solve any problems
besides bitcoin, Xiaotao has always been a loser of bitcoin, because in Xiaotao's view, bitcoin has not solved any new problems. In other words, what would the world lose without bitcoin today? Who and which transactions will be affected? The answer is that no one will be affected except the most special people. What are the advantages of bitcoin over existing currencies? Stable currency? Security? Low cost
the decentralization advocated by bitcoin is nothing more than evading regulation. For example, the goods between the two countries should have gone through the customs. The Customs has eight channels. Now you have an underground channel. Although the distance may be closer and many customs ties may be exempted, it is illegal. It is a typical Arbitrage Behavior to evade supervision. Solving one's own problems on the premise of harming social interests and order is not desirable and can not last
What's more, in order to obtain bitcoin, the huge "mining" workload consumed a lot of power and computer computing power, and did not create any value, which is a huge waste of social resources. It is said that the cost of digging a bitcoin has reached 3000 to 4000 US dollars...
"ICO" is a typical Ponzi scheme
as for ICO, the so-called IPO project with digital currency as the media, sticking to its own hot speculation concept, holding the idea that it is not ready to cash, or the idea that the feasibility is almost invisible, relies on a kind of digital currency that evades the supervision to let people buy and hype the price... This is a typical Ponzi scheme, or open a casino in disguise
there are many such cases in history. A few years ago, some people divided any painting into tens of thousands of shares, marked a price for everyone to buy and hype; Hundreds of years ago, the Dutch were crazy about tulips. A tulip price could buy a castle... Everyone knew that it was a bubble. They all knew that the bubble would burst, but everyone wanted to beggar the neighbour, hoping to get a.
before the bubble burst.
