Digital currency 500 yuan

1. 2020 is the first year of proction rection. Everyone turns to BTC, BCH, BSV and other currencies. However, you forget eth. As the king of the public chain, ETH will usher in the big upgrade of 2.0 super version in 2020, switching from the pow mechanism to the POS mechanism. In addition, it will face proction rection in March next year, and its circulation will be reced by 10 times. Its impact is no less than that of bitcoin proction. Since the beginning of the year, the trading volume of eth has grown explosively, and the institutional capital has poured in to preempt the layout. However, the current price of eth is only 260 US dollars. With many super favorable blessings, the market expects eth to usher in a super bull market< In theory, X2
2. The circulation of next year will decrease 10 times. In theory, X2
3. The current price of eth is 230x4 = 920 US dollars (upgrade + expected price after proction rection)

ring this period, the return comparison between holding spot and ETF fund is as follows:

1. Holding spot makes 4 times of profit
2. Holding Ethereum ETF fund launched by bitoffer, the income starts 12 times, Up to 30 times (intelligent position adjustment + fund compound interest calculation)

there is no doubt that Ethereum ETF is the best investment choice!

2. For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency

virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency

in 2013, the central bank, together with five ministries and commissions, issued the notice on preventing the risk of bitcoin, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, not in the form of currency and legal currency< At the same time, digital currency is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.

Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies

digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank

it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography

4. As a blockchain digital currency practitioner, to answer "first of all, you need to understand how bitcoin comes from. I hope the following answers will help you
what is blockchain
blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust
generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book
so what's the difference between our current accounting method and blockchain
take the Internet giant companies as an example, wechat's account book is Tencent's account book, and Taobao's account book is Alibaba's account book
but in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
will not mastering blockchain be eliminated by the times
although blockchain is popular, for ordinary people, they don't need to panic and can't master this technology. In fact, it has nothing to do with us. After the implementation of blockchain development, we only need to be able to use related applications. Just like we don't need to know what is the underlying TCP / IP protocol of the Internet, we just need to enjoy the services provided by the Internet. Blockchain is more similar to the underlying technology such as TCP / IP, and will be extended to more and more instries in the future
how to apply blockchain
the most important thing of blockchain is to solve the problem of intermediary credit. In the past, it was difficult for two people who didn't know and trust each other to reach cooperation, and they had to rely on a third party. For example, in the past, there must be an institution such as a bank or Alipay.
therefore, blockchain can subvert many instries, making these instries without intermediary participation, efficient and transparent process, low cost and high data security. Therefore, if there is any demand in these three aspects, the instry will have the opportunity to use blockchain technology
what is bitcoin? Is bitcoin a blockchain
blockchain technology is the underlying technology of bitcoin. Through the blockchain technology, bitcoin is the first time for human beings to realize the mutual trust transfer behavior without the participation of any intermediary. And this system has been running autonomously and stably for many years, and there has been no problem
therefore, many people have noticed that the underlying technology may have a great mechanism, and it can be used not only in bitcoin, but also in many fields. Therefore, bitcoin technology is abstracted, which is called blockchain technology or distributed ledger technology. So from a certain point of view, bitcoin can be regarded as the first application of blockchain, and blockchain is more similar to the underlying technology such as TCP / IP, which will be extended to more and more instries in the future
what is "mining"
mining, in a narrow sense, is the "mining" in bitcoin. The operation of bitcoin adopts a mechanism called "proof of work (POW)". In order to find out who has more powerful computing power, the system will work out a mathematical problem every time. Only the computer that can solve the problem the fastest can carry out accounting. The computer that grabs the bookkeeping right will be rewarded with 25 bitcoins. This behavior is usually called "mining", and the bitcoin obtained is regarded as the reward for successful mining
broadly speaking, it is a process of bookkeeping reward, which can be used in any instry or digital currency
what is smart contract
smart contract is a kind of contract that uses computer language instead of legal language to record terms. Smart contracts can be executed automatically by a computing system. If blockchain is a database, smart contract is the application layer that can make blockchain technology applied to reality. In the traditional sense, the contract has no direct connection with the computer code to execute the content of the contract. In most cases, paper contracts are filed, while software executes contract terms written in computer code. The potential benefits of smart contracts include lower contract signing, enforcement and regulatory costs; Therefore, for many contracts related to low value transactions, this is a great rection in labor costs
Q: how to use smart contracts
if the central bank can issue legal currency through blockchain, it can also embed code into the behavior of issuing legal currency through smart contract technology, and this part of legal currency can be called "programmable currency". For example, if the Central Bank specifies that a certain part of the fund is issued to the agriculture related account, then it can write the corresponding proceres for this part of the fund, and specify that this part of the fund can only enter the agriculture related account, then this part of the fund can not be misappropriated to other accounts under any circumstances. If most currencies become "programmable currencies", then we can imagine that the financial environment they form will become "programmable finance"
what is digital currency
digital currency refers to the digitization of currency. Digital currency can be divided into two types: non cryptocurrency (e-gold, XRP) and cryptocurrency (bitcoin)
digital currency is often mistaken for virtual currency. But virtual currency refers to non real currency. For example, when you play "Three Kingdoms" (game) or "grand Voyage", you have money, and that money is virtual. Of course, the virtual money will also have its real value. For example, if you buy her / his account from another player, you can get all the virtual assets of that player, and then it will be much easier for you to continue playing
does a blockchain project need to have some kind of currency
A: No. Bitcoin itself is a payment system, so it needs a value measurement tool, so bitcoin must appear. In addition, in order to reward more people who are willing to contribute their computers to provide computing for the system, bitcoin is needed. In some private chain systems, special assets can be designed for transaction, and each node must participate

5. The calculation force obtained is that of URU

6. GEC environmental protection coin is issued by swindlers. How to set it? Swindler customer service!

7. Digital money is just like WeChat Alipay bank card. WeChat Alipay is only owned by Ma Yun and then to the country. Digital money is directly controlled by the state.

8. Pay for a lesson system

Compared with Europe and the United States, our price level is really not too high, and according to our current consumption habits, there is no need to issue large amount of money, this does not have a good impact on our current life, it does not simply facilitate people's consumption, but promotes the emergence of inflation{ RRRRR}

we are now popular in virtual payment, online payment basically does not use too much paper money, if the city supports this kind of online payment, maybe everyone will use very little paper money all year round, most of them are 10 20 100 , There is no need to use 500 pieces of banknotes
