Bitcoin trading in the world
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
1. Legal currency transaction: that is to buy, sell or trade digital assets through legal currency. For example: bitcoin now quote 6 in case, then whether it is credit card or Alipay WeChat, anyway, buying money directly is the legal tender transaction.
2. Currency currency transaction: mainly for transactions between virtual currency and virtual currency, one of which is used as the pricing unit to purchase other currencies. Its trading rules are also based on price priority and time priority
3. Leverage Trading: it is to invest several times of the original amount with small amount of funds. In order to obtain the relative investment object volatility multiple yield, or loss. As the increase or decrease of margin does not move in proportion to the fluctuation of underlying assets, the risk is very high
4. Contract trading: contract trading is the general term for the futures contract trading of the 796 exchange in comparison with the special currency. In June 2013, 796 exchange took the lead in developing bitcoin weekly delivery standard Futures - t + 0 two-way trading virtual commodity barter contract (contract trading) in bitcoin instry
warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly 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

Bitcoin trading platforms include Mt. goxmt, bitstamp, bitcoin China, bitcoin trading network, fire coin network, etc
however, to say a good thing, it depends on whether it is safe and reliable enough, whether the trading experience is smooth enough, and whether the currency is complete enough. From these dimensions, the security of the current mainstream centralized exchanges is not up to standard, and coin loss and theft often occur. In contrast, the decentralized exchange has achieved rapid development in the past two years. In particular, the head of the decentralized exchange has done a very good job in terms of user asset security and user experience, and the good experience can be comparable to that of the centralized exchange. It is believed that with the development of technology, decentralized exchanges will graally become the mainstream, and centralized exchanges will graally withdraw from the historical stage. The trading platform is better to be decentralized, such as me.

the law of integer multiplication is extended to fractions, so that students can feel the subtle relationship between the multiplication of fractions by integers and the addition of fractions with the same denominator
2. Remember the pithy formula well
brackets should be calculated first with brackets, from front to back without brackets, multiplication and division first, and then addition and subtraction
3 Clear the concept
let students understand that the reciprocal of an integer is one of the original fractions, and the reciprocal of a fraction is to exchange the numerator and denominator
