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!

Ant technology is almost zero cost financing, through various forms of packaging debt, repeated borrowing, and then irresponsibly lend money to young people who have no ability to repay. This is basically bringing the crazy financial crisis of Wall Street in 2008 to China. The real capital market is changeable and more cruel than you think
ant technology's blood sucking through online loans has been picked out by many people. Zhou Xiaochuan, former governor of the Central Bank of China, also said at the Boao Forum of Asia recently that Internet technology giants controlled a large amount of data and market share, formed a monopoly and hindered fair competition, which led to the decline of Alibaba's share price
if Google can freely use users' personal information in financial business, it can also become the largest lending institution in the world. Google doesn't do it because American businessmen are particularly kind, but American policies don't allow it at all
as vice minister of Finance Zhou Jiayi said at the Bund financial conference, science and technology has not changed the nature of relying on credit to use leverage, supported the development of financial technology, insisted on the improvement of science and technology, prevented financial technology from incing excessive financial consumption, and encouraged the winner take all monopoly
now that the digital currency DCEP of "central dad" is on the way, can ma Yun's wishful thinking work well in the future? Let's wait and see< br />
3. Digital currency platform development needs professionals to be responsible for, but now digital currency technology has matured, the difficulty of development has become very simple, has become a standardized technology. Today's digital currency technology is not the highlight, but the application scenario of this kind of digital currency
the birth and popularity of bitcoin all over the world depends on the concept, which is in the foreword of the times. However, bitcoin has been preconceived and cannot be replaced by other digital currencies. Although some counterfeit currencies were popular for a while later, they slowly went down in the end, only bitcoin strengthened. Puyin is another shortcut, as a standard system of digital currency appears, behind the endorsement of related tea assets, its value is recognized by the society.

4. Friends who are new to the currency circle are dazzled to see all kinds of digital currencies. What are the origins and characteristics of these cryptocurrencies? Here is a brief introction to some mainstream cryptocurrencies< Bitcoin is the earliest cryptocurrency. In 2008, an Internet geek named Nakamoto Tsung published a paper called bitcoin: a peer-to-peer e-cash system. In 2009, the first creation block was g up by Nakamoto Tsung and has been developing ever since. The original block size of bitcoin was only 1m, and the congestion problem was getting more and more serious. As a result, the block expansion was put on the agenda. The core development group advocated the use of isolation witness and lightning network to realize the expansion, while the big block group advocated the direct expansion of the block. At last, on August 1, 2017, bitcoin cash (BCH) forked from bitcoin (BTC) and expanded its capacity by expanding the block. After this split, bitgold, bitdiamond, super bitcoin, bitgod and many other split coins have sprung up. Later, BCH itself encountered a bifurcation. The Australian CSW, who calls himself Nakamoto Tsung, has to continue to expand the block and lock the underlying protocol of bitcoin. He claims to make a bitcoin that meets Nakamoto Tsung's vision. This time, the bifurcation coin is called BSV
apart from BCH and BSV, most of the other bifurcated currencies have declined. BTC, BCH and BSV represent the exploration of three different directions respectively. BTC is the most conservative and cautious, BSV is the most radical, and BCH is relatively mild and graal. At present, BTC enjoys the name of bitcoin in fact and has the largest market value< br />
< At the end of 2013, vitalik buterin (V God), a gifted programmer born in 1994, published a white paper on Ethereum, proposing the idea of adding various smart contracts to cryptocurrency, which can be used in social networking, trading, games and other fields. The market value of Ethereum has soared all the way, and it will soon be second only to bitcoin, Ethereum with smart contracts is also known as blockchain 2.0
in 2016, Ethereum encountered a serious hacker coin theft incident (DAO), and God V decided to delete the coin theft record by using rollback method. However, some people who insisted that the blockchain should not be tampered with opposed rollback, so Ethereum also split. Unlike bitcoin, the original Ethereum chain has become a minority, known as the Ethereum classic (etc), and the new chain that has been rolled back has become a majority, the de facto Ethereum (ETH)
stable currency system
stable currency is generally anchored legal currency, which can be used to exchange legal currency 1:1 to the issuer. The currency value is relatively stable, but sometimes there will be a small amount of premium in transactions, which is widely used in cryptocurrency transactions. Now the most common stable currency is the usdt issued by tether company, 1 usdt = 1 dollar. Stable currency is generally issued on other cryptocurrency networks, such as bitcoin Omni protocol, Ethereum erc20 protocol, etc< br />
in anonymous currency
on bitcoin, every transaction is clear and searchable, although we don't know who the person behind the address is. Some people think that the privacy of bitcoin is not enough, so some anonymous coins, such as XmR, dash and zcash, which can cover up user information, have emerged. Monroe coin uses ring signature technology, dasey coin adopts mixed coin technology, and big zero coin uses zero knowledge proof, which can play an anonymous effect in different degrees
platform currency system
some digital currency trading platforms often release their own platform currency, and there are certain discounts for trading with platform currency, such as okb of okex, HT of fire currency, BNB of coin security, etc<
some other mainstream currencies
lightcoin (LTC) has copied the code of bitcoin, replaced the consensus algorithm, and shortened the block out time. When bitcoin wants to upgrade, it often does experiments on bitcoin first. Lightcoin is known as "bitcoin, lightsilver"
XRP is currently the third largest currency in market value. It is an Internet transaction protocol, allowing users to transfer money around the world quickly and cheaply
grapefruit coin (EOS), known as blockchain 3.0 and Ethereum upgrade, attempts to introce more functions and application expansion on it

"bitkangaroo" is the first digital currency financial service platform in the world that allocates theoretical revenue from its own mines and machines without power failure. The platform is mainly based on cloud computing procts, and the theoretical revenue is allocated by "1tash" of Wanyou computing power's professional mine, a strategic partner, on a regular basis every day, integrating high-yield, security, liquidity, transparency and professionalism
High Yield: the platform aims at "increasing users' assets", and customers can choose a variety of derivatives to prevent systemic risks
Security: the team stores the standby digital assets in the cold multi signature wallet, and in case of any accident, the reserve fund will be used to distribute revenue to customers
Liquidity: the platform allocates income every day, and can withdraw as soon as it reaches the minimum currency withdrawal standard
transparency: mine data and mine logs are open and transparent, and users can monitor the actual computing power of the mine at any time through the data center monitoring system
Professional: the mine is operated and managed by professional personnel who have been engaged in deep mining for many years. Each unit is isolated by professional network interruption to prevent virus invasion. Multiple standby networks are used in the computer room to eliminate non systematic risks in an all-round way

In recent years, digital currency has appeared frequently in the public's view. Shenzhen Luohu has also followed the trend and announced the release of 10 million digital red envelopes. How can we get the digital red envelopes this time
this activity is aimed at the vast number of indivials in Shenzhen. The total amount of RMB 10 million will be issued, with 50000 red envelopes and 200 yuan each
after receiving the digital red envelope, more than 3000 merchants in Luohu District can freely use it within the validity period of the digital red envelope. However, digital RMB can not be lent to others or cashed directly, and the digital currency will be withdrawn if it exceeds the validity period
it can be said that this way of giving back to the public is also a way to promote regional economic development. In the future, more and more places will use the Internet, and electronic red envelopes will become the mainstream
therefore, the way to get the red envelope is still very simple, but the probability of winning the prize is not very high, so it's time to rely on luck. I hope that all the little friends who read this article will have good luck and get a big red envelope of 200 yuan
6. The issue of bitcoin is determined by the block height, that is, the distance from the No. 0 block of Genesis. Now when the number is reached, the total amount of bitcoin should be limited. After this village, there will be no store. If the miners dig a block but don't receive the reward of the block, the bitcoin will be destroyed forever
coinbase transaction is a special transaction that generates bitcoin "out of thin air". Only miners can write this kind of transaction, and the number of generated bitcoin is limited by rules (new currency reced by half for every 210000 blocks + transaction fee for this block)
however, the rules do not stipulate that the miner must take away all the rewards that can be taken, and can choose not to take them
therefore, a mine pool connected with the RSK side chain has made a bug before, forgetting to take away the reward and occupying a pit in a block for nothing, which is equivalent to destroying the corresponding amount of bitcoin, making the total amount of bitcoin decrease a little bit permanently
in addition, to spend a bitcoin, you only need to specify the transaction ID and output serial number
as like as two peas in multiple blocks repeatedly write identical coinbase transactions, the transaction ID is also repeated.
therefore, this kind of situation also occupies the pit of a block in vain, and permanently destroys the corresponding amount of bitcoin
it seems to me that this is still a security vulnerability, so the new version of bitcoin software later banned the writing of repeated coinbase transactions. But until now, there has been no ban on miners not getting their e rewards
generally speaking, a coin is controlled by a private key. If a coin is transferred to an address where no one knows the private key, it will be destroyed
if the owner does a good job in security, and the private key is not disclosed and cannot be guessed, but he accidentally loses the private key, it is equivalent to destroying all the coins he owns
there are only some special circumstances that require intentional destruction of coins
one is irreversibly converted into another kind of currency, such as the contract currency XCP attached to bitcoin and wormhole cash WHC attached to BCH
the second is to save certificates and data on the chain, such as the time stamp: panbiao.com/2013/08 /
and the crowd funding of the original Ethereum founding team: zhuanlan.hu.com/p/29
the private key is essentially a big number. Whoever knows this number can control the currency on the corresponding address. So the private key must be generated with reliable random number, otherwise it may be guessed and stolen
compared with the token, the address is the hash of the public key. There is no way to judge whether an address has a corresponding public key and private key (even if the public key is known, the corresponding private key cannot be known). Therefore, even if it is explicitly the address of "burned" token, the system does not prohibit the transfer in
strictly speaking, what locks the currency is a small program (script). This program takes the input as the public key and digital signature. First, check whether the public key hash is consistent, and then check whether the digital signature is valid. If it is valid, it will be verified and transfer is allowed; Otherwise, it will be judged that the transaction is illegal and refuse to package into the chain
it is the whole node software that explains and executes this program. It can be said that the software code of the whole node specifically defines a coin
however, the current situation is very embarrassing. Most miners do not run the whole node, only a few mines are running. The vast majority of users do not run the whole node, even if they run the whole node, they can only perform verification, no computing power, no block.
