The space of digital currency chain

1. What is digital currency? Is it the same thing as electronic money and virtual money
the difference between digital currency, electronic currency and virtual currency
in fact, digital currency is a kind of indexed RMB, a legal encrypted digital currency and an alternative currency in the form of electronic currency. Digital currency can be divided into two types: non cryptocurrency (e-gold, XRP) and cryptocurrency (bitcoin)
it can not be completely equivalent to the virtual currency in the virtual world, because it is often used for real goods and services transactions, not limited to online games and other virtual spaces. It is different from Alipay and WeChat, and Alipay, WeChat payment and mobile phone banks are all electronic money, not digital money. The popular digital currencies in 2016 include bitcoin, lightcoin, bitstock, etc. At present, there are thousands of digital currencies issued all over the world
virtual currency refers to the non real currency, especially the currency in the network virtual economy. The issuer is not the central bank, and it can only circulate in a specific virtual environment. In the case of the connection between virtual and reality, virtual currency has its real value. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point, roll counting of Shanda company, u-coin meter ticket launched by Sina (used for igome game), chivalrous Yuanbao (used for chivalrous road game), and grain silver (used for bixue Qingtian game). Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency. For example, bitcoin is illegal digital currency
since the beginning of the year, the relevant person in charge of the people's Bank of China has said that the future of mobile payment is bright, and the central bank is actively studying the relevant research results and practical experience at home and abroad to strive for the early issuance of digital currency. At the digital currency seminar of the people's Bank of China held on January 20, the relevant person in charge of the people's Bank of China disclosed that the central bank has set up a special research team since 2014 to conct in-depth research on the digital currency issuance and business operation framework, key technologies, circulation environment, etc., and strive to launch the digital currency issued by the central bank as soon as possible. At present, the research has achieved phased results
what benefits will digital currency bring to our lives
for this problem, the relevant person in charge of the central bank said that if the digital currency is successfully issued, it will bring many conveniences: it can effectively rece the high cost of the issuance and circulation of traditional paper money, and improve the convenience and transparency of economic transaction activities; It can rece money laundering, tax evasion and other illegal and criminal acts, enhance the central bank's control over money supply and money circulation, better support economic and social development, and help the comprehensive realization of Inclusive Finance; It helps to build a new financial infrastructure, further improve the payment system, improve the efficiency of payment and clearing, and promote the upgrading of economic quality and efficiency. More digital currencies can focus on bitMom

2. In fact, the digital money market can be simply called the currency circle. It is said that one day in the world and one year in the currency circle. In fact, it is neither big nor small. As long as it is still the currency circle, the reliable trading platform is the internationally famous Pt currency

3. Introction: Wanxiang blockchain is a blockchain related company invested by Wanxiang blockchain

4. I suggest that we all have a fixed team. We should have a fixed team. We should have a fixed team. We can talk about important things three times and consider joining the guild. Fixed team recommendation: Tieyi (currently the only t), Xuehe, suimeng, Jiuling, Shenxiang, Suwen (currently the only milk). Game currency difference: Copper money can be traded, jiaozi cannot be traded
the daily refresh time is changed to 6:00, and the weekly (guild task) refresh time is 6:00 every Sunday< First, upgrade strategy:
first, do the main line task, then the card level will do the branch line or daily (new number, go to the level, and then in any order). After reaching level 50, first experience the book (Marquis order, Vientiane tower) and then the main line / branch line
the main line / branch line demon monk (the same demon monk can only play 5 times in a week, and can get chivalrous points without reward after 5 times) gains items: red dress and low probability purple dress (team move brick task).

5. The above formula is not perfect, because the direction of wind speed is not necessarily perpendicular to the action surface θ
F= ρ S(v*sin θ)^ 2
the formula is deced as follows:
consider the case that the wind speed is perpendicular to the action surface first
take the cross section of the wind as s and the length as S Δ x( Δ x-> 0), and the velocity before the wind contacts the action surface is v Δ x=v Δ T
the mass of the air column is Δ m= ρ S Δ x= ρ Sv Δ T
because the mass of the air column is very small, when it collides with the action surface, it will move along the action surface, that is, its velocity perpendicular to the action surface is 0 Δ t=0-(- Δ MV)
i.e. F Δ t= ρ Sv Δ t*v
F= ρ When the wind speed is not perpendicular to the action surface, the velocity is divided into the direction of the vertical action surface and the direction parallel to the action surface. Since the component parallel to the action surface will not generate force with the action surface, the final wind force is only the component perpendicular to the action surface, which is v * sin θ, Substituting this formula into (*) to get
F= ρ S(v*sin θ)^ two

6. Both domestic Shenyu mine and bitcoin mine in China are OK. Of course, there are many well-known mines abroad that can be mined. You said that the software is now a long time ago, when the configuration of a higher computer or graphics card mining, more trouble. Now if you are still mining those equipment, I suggest you do something else meaningful. Now we need to buy professional ASIC mining machine. Even so, it is difficult for retail investors to recover their capital. Of course, you can also buy cloud computing power mining. Now mining is fighting for electricity price and energy consumption. If these two points have advantages, mining is OK. If these two points can't be achieved, it's no use. Of course, it doesn't rule out that the electricity charge you add is free. This can also be mined

you need to download a bitcoin wallet and back it up. Just keep bitcoin in your wallet. However, if you don't know the technology, I suggest you store bitcoin in your online wallet. Now the technology of online wallet is very mature. If you still don't understand, go to bitcoin home to see some suggestions from netizens.

7. It's still very impressive. Ght has bitcoin, grapefruit and other digital currencies that have existed for a long time,
