Computer playing virtual currency
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. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
Internet currency of Internet company, QQ currency of Tencent company, q-point, voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), and silver pattern (used for bixue Qingtian game)
network virtual currency can be roughly divided into:
the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as bitcoin (BTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency

strict law enforcement:
(23) enterprises engaging in online game virtual currency issuance and trading services without permission shall be investigated and dealt with by cultural administrative departments at or above the provincial level in accordance with the Interim Provisions on Internet culture management
(24) for the online game virtual currency issuing and trading service enterprises that violate the requirements of this circular, the cultural administrative department and the competent commercial department shall notify them to rectify within a time limit. Those who fail to rectify within the time limit shall be investigated and dealt with by relevant departments according to law (25) establish a coordination mechanism for the management of virtual currency in online games, and intensify the crackdown on illegal activities such as "number theft", "private service", "plug-in", illegal profits, money laundering, etc. All departments should regularly communicate, coordinate and cooperate with each other, timely report the relevant situation, and do a good job in the management of online game virtual currency within their respective responsibilities (26) the online game virtual currency issued by the online game operation enterprise shall not coincide with the name of the props in the game. The administrative provisions for props in online games shall be formulated separately by the cultural administrative department of the State Council in conjunction with relevant departmentssource: Internet virtual currency
Some new virtual digital coins can be mined by computer, such as eth, Zec, Monroe, XRB, etc
because the whole network computing power required by this kind of token is not high, the probability of hash collision of the computing power of personal computer can find out the answer in a short time, so as to obtain the block reward. However, this kind of token generally has little value, or has no high risk, so it doesn't mean much
extended data:
mining risk:
1. Electricity charge:
to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
2. Hardware expenditure:
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and mining has a considerable expenditure
in addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation, and the computing power is quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the power cost is also lower. It is difficult for single chip display to compete with these mining machines, This kind of machine costs more
3. Currency security:
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
4. System risk:
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income
however, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
it used to be better, but now bitcoin is no longer what you want to dig.
many people have begun to sell mining machines
1. The calculation is mainly done by GPU, while the GPU of ordinary computers is not very powerful, which directly leads to low mining efficiency, and even the electricity bill can not be recovered
2. Because it is used to exchange data on the network, not only the performance of the computer should be good enough, but also the network bandwidth and quality should be higher. If you are asked to build a telecom 100 MB broadband before, I wonder if you are still so interested
3. GPU will generate a lot of heat ring calculation. If it is not handled properly or the original radiator is very dirty, it may burn the GPU or computer, and the gain will not be worth the loss
4. The other is the impact of the environment. Let's not say where bitcoin is going to go, let's say that the current exchange rate is seriously declining and there is no money to make before. Professional mines are even processing equipment. It's obviously unreasonable to go mining at this time
of course, if the computer is not yours, you don't have to pay for the electricity, and broadband doesn't need money, then you can try it....
you can't change the data in the remote server
