BTC bitcoin
bitcoin is the first distributed digital asset platform created. Since its launch in 2009, it has proven to be not only the most popular, but also the largest market capital value. In addition, it is also the most expensive, with a value of $10710 per coin on February 17, 2018. Bitcoin introces the first blockchain distributed ledger dedicated to recording all transactions, and gets rid of the function that users need a central authority to process or verify transactions
its goal is to provide a platform for users to conct cross-border transactions without any intermediary, which is what we call decentralization. The platform's largest money (BTC) supply is about 21 million. Of this figure, about 16.5 million have been mined and are now in circulation. It is mined all the time around the world to ensure the circulation of coins
Advantages:1. Its distributed system provides users with great freedom
2. High portability

eth Ethereum
Ethereum is also a distributed platform, which was created by Network Programmer vitalik buterin in July 2015. Ethereum aims to enable users to create and deploy smart contracts. One of the main functions of smart contracts is to allow the creation of encrypted assets or tokens running on Ethereum networks. Ethereum token is used to purchase various functions such as cloud storage space. These tokens are stored in a digital wallet compatible with Ethereum blockchain
Ethereum's digital currency ether serves as the medium for executing smart contracts. At present, about 98 million ether coins have been mined and circulated, and the circulation supply increases by about 18 million every year. Ethernet coin is created to run on the Ethereum network. It can be used to compensate the participant nodes or transfer from one user to another

< H2 > extended data:generation principle:
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique
in the metaphor of banknotes, bitcoin is the number of the top word of a banknote. The number of the top word on a banknote owns the banknote. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
after completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to post the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)
the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"
Ethereum will open at $225.03 on July 22, 2019.
Yingtai Digital Theory: after the implementation of digital currency, it will coexist with banknotes and coins for a long time. Whether it can completely replace banknotes and coins in the future is still unclear
of course, with the implementation and graal maturity of digital currency, the use of digital currency will be more and more, and the use of banknotes and coins will be less and less. These banknotes and coins will slowly enter commercial banks through residents' storage or exchange of digital currency, and then commercial banks can use them to exchange digital currency with the central bank
1. Stamp ty: 1 ‰ of transaction amount. At present, it has changed from bilateral levy to unilateral levy on the seller. The tax paid by investors to the finance and taxation department after the transaction. Shanghai stock and Shenzhen stock are paid at 1 / 1000 of the actual transaction amount, and the tax is dected by the securities dealers and paid by the exchange. Bond and fund transactions are exempt from this tax
2. Securities supervision fee (commonly known as three fees): about 0.2 ‰ of the transaction amount, and there is a mantissa in fact, which is generally omitted as 0.2 ‰
3. Securities transaction handling fee: a share, 0.087 ‰ is charged bilaterally according to the transaction amount; For B shares, 0.0001% will be charged bilaterally according to the turnover; Fund, bilateral charge 0.00975% according to turnover; For warrants, 0.0045% will be charged bilaterally according to the turnover
4. Transfer fee (only for Shanghai stock): This refers to the fee to be paid for changing the account name after the stock transaction. Due to the different operation modes of the two exchanges in China, the Shanghai stock exchange adopts "central registration and unified custody", so this fee is only paid by investors in Shanghai stock and fund transactions, but not in Shenzhen stock transactions. The fee shall be paid at one thousandth of the face value (per share) of the traded shares, and less than 1 yuan shall be charged at 1 yuan
5. Commission for business transactions: the maximum is 3 ‰ of the transaction amount, and the minimum is 5 yuan. Commission for a single transaction less than 5 yuan will be charged as 5 yuan
