2. virtual currency, or more formally, digital currency. Although it carries the words of currency, it should be a kind of digital financial asset. Its value comes from the application of blockchain technology in payment, clearing, notarization, digital verification and other aspects, which brings efficiency improvement and cost rection
as you can understand it, it's like the stock of these technology service providers. As these technologies become more and more widely used, these virtual coins will become more and more valuable
bitcoin, which appeared in 2009, is the first kind of virtual currency in the world. It is also the first time that it has applied the blockchain technology which is popular all over the world
after bitcoin, there are many imitators in the market. They either improved on the basis of bitcoin, or put forward more grand technical ideas than bitcoin. Virtual currency, which is common in other markets and considered as "regular army" by instry insiders, is collectively referred to as competitive currency. Together with bitcoin, it forms the whole digital currency market, with a total market value of nearly 100 billion US dollars
there are thousands of virtual currencies in the market, most of which are risky; In addition, there are many MLM coins that are simply for the purpose of deceiving people< In order to help you avoid being cheated, the following is a brief introction to the main "regular army":
1. Bitcoin (BTC)
bitcoin is the first virtual currency in the world, with a total of 21 million. At present, more than 16 million bitcoins have been "g up", with a total market value of about US $45 billion, equivalent to half of the total market value of all virtual coins. It is well deserved to be the number one in the coin circle
bitcoin has been accepted as payment currency by hundreds of thousands of businesses around the world; In addition, bitcoin has also become a common money raising currency in various blockchain technology startups. Therefore, with the increasing demand for bitcoin, the value of bitcoin is likely to grow in the long run
2. Eth is regarded as "bitcoin version 2.0" and is the most likely competitor to surpass the market value of bitcoin. Some time ago, the market value of bitcoin was close to that of bitcoin. However, e to the price rection in the recent month, the market value of bitcoin is only about half of that of bitcoin
Ethernet coin was born in the summer of 2014. It is issued on the Ethereum blockchain, which is different from bitcoin. Ethereum blockchain is a decentralized application platform, which solves the problems of bitcoin's technical limitation in currency application and insufficient function expansion, so it has great technical advantages
3. Bitcash (BCH)
BCH inherits a small part of bitcoin's legacy, the name of bitcoin's cash is also good, and the image logo also inherits a part of bitcoin. The ecology of BCH is also good
BCH pursues to be a world currency and an underlying platform for chain application. BCH is actively deploying the main chain expansion and developing the two-tier network to realize the ideal
the whole ecology should be made efforts from two aspects. The first direction is the expansion of the main chain, payment experience and function improvement. Capacity expansion is the guarantee to keep the certainty of monetary transaction fees very low. Improving the payment experience, including popularizing zero confirmation, pre consensus, and possibly shortening block time, are all evolving towards a better payment experience. The main chain function is perfect, including Op_ Return expansion, token issuance, new opcode addition
with the expansion of BCH main chain function, BCH based applications can be developed. The most famous are the decentralized microblog like memo, the paid download seed application like joystream, and the decentralized encrypted communication like Keyport
the second direction is to develop layer-2 network. Build a new blockchain based on BCH network, such as wormhole and kenoken, which are similar to Ethereum network based on BCH. BCH undertakes more complex block chain functions, such as notification contract, through two-layer network. The competition direction of BCH layer 2 network is to compete with the side chain of BTC
4. Lightning bitcoin (LBTC)
bitcoin has been developing for 10 years. In this decade, bitcoin has experienced three important splits, and now it has become four kinds of currencies. The first is BTC, which has inherited most of bitcoin's heritage; The second is BCH; The third is BSV and the fourth is LBTC
LBTC was born to break the power monopoly of big miner and bitcoin core bitcoin, introce more new features and functions for bitcoin, and greatly improve its performance. Lightning bitcoin (LBTC) is a peer-to-peer e-cash system, which is an innovative experiment based on bitcoin. It uses the dpos consensus mechanism based on utxo to separate the voting right and accounting right, so that the token will not be kidnapped by any party. It is a global value Internet transmission protocol with high speed, low handling charge and high scalability. Due to the adoption of dpos consensus mechanism, users can participate without professional mining machines, achieving real decentralization
the above four are the most mainstream bifurcated versions of bitcoin protocol. They are also investment procts that can realize your desire of soaring wealth. Senior managers can play with them, but the premise is that you need to be prepared for huge losses - because they are very volatile
for Xiao, I would like to say: Although virtual currency is a secret weapon for ordinary people to counter attack the sudden wealth, it's very difficult for you to make a lot of money from it
in addition, at present, the price of virtual bitcoin is at a high level, and it can not be ruled out that it will mainly be sideways in 2019. At this time, I think it is a good choice to some other mainstream bifurcation currencies, such as BCH, BSV and LBTC.

3. Bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
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 a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design 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.

4. The issuance of futures and other derivatives will expand substantially. The debate on whether derivatives trading is stable or undermines the stability of the underlying market has lasted for decades, with dozens of papers written by leading economists. A 1976 paper analyzed the onion and potato futures market and concluded that derivatives, in fact, tend to have more and more proction shocks on the price, thus recing the volatility
this paper analyzes the same problem with bitcoin: the futures market has been launched for some time, allowing researchers to draw preliminary conclusions on its impact. The researchers found that the effect was not linear: Although the first trading period actually led to higher volatility, then graally declined, establishing a strong causal relationship in the last period
"from a professional perspective, market makers prefer to use settled and closed markets; Material object; Contracts to hedge futures contracts, thereby greatly recing the risk of potential settlement price manipulation, "he explained“ Through a cash settlement contract, the settlement price will never really be effective at maturity. "
the difference between cash settlement and physical delivery futures is how to deal with the underlying assets: in the former, transactions are only written off mathematically according to the reference spot price, while in the latter, the assets are actually e
"as a result, the buyers of these [cash settled] contracts seem to be speculators, using leverage," he continued“ Once the long-awaited physical contracts are listed, I expect most cash settled contracts will lose their attractiveness and the spot market will stabilize. "
at the end of last week, the trading price of bitcoin was in an incredible state of tension. Bulls failed to take charge of cryptocurrency, while the market was quite good. As pointed out earlier, when bitcoin trades at a smaller price in a very short period of time, a breakthrough move is likely to come
for most of this month, Ethereum enjoyed a strong upward movement over the weekend after the territory was depressed. Looking at the ETH / BTC chart, it seems that cryptocurrency has surpassed bitcoin in the short term, despite the warning of MACD index that there may be a bearish correction soon
the level of $10000 is the key support area that sellers need to break through this week. The weakness in this key technology area may be the trigger for the bearish attack on BTC / USD against the current monthly trading low
in the short term, it is important for sellers to force the price to be around $10260 at the weekly fulcrum to gain control over the price action, and to encourage testing of the previous week's trading lows of BTC / USD pairs.

5. Ha ha, it seems to be a little crooked after a long time's observation
it can only show that the proct inspection of the mobile phone case supplier is not good,
however, it should also be within the error range,
as long as it is a new machine, it will be OK
to see if it has just been activated

6. There are two key points in writing: one is the structure of the frame, the other is the method of using the pen. The frame structure refers to the arrangement of strokes
your strokes and structure need to be improved.

7. A little bit to the left, there is no problem to be a soldier. In the future, you should pay attention to your sitting posture and not be paralyzed by the sofa. After standing posture training, your side bend will be corrected. If you are still worried, you should go to the hospital to consult, and don't delay the conscription.

9.

When reversing, the car body will look askew at the direction of reversing, which is summarized as follows:

1. If it comes in from the left, turn the steering wheel to the left in advance. If the left side is narrow, delay turning the steering wheel to the left side

2. If it comes in from the right side, delay turning the steering wheel to the right side; If the left side is narrow, turn the steering wheel to the right ahead of time. If the car touches the line on the left side of the tail after backing into the warehouse, one is that the car body is not straightened before entering the warehouse, and it is too late to return to the right direction

10.

When the novice asks for reversing, the rear wheel should be subject to the rear end of the rearview mirror. The specific skills of reversing and entering the warehouse are as follows:

1. When the vehicle runs to the lower edge of the left rearview mirror and touches the control line, the steering wheel will turn right
