2. In 2009, Nakamoto Tsung invented bitcoin, and he designed the issuing mechanism of bitcoin:
the issuance of bitcoin does not depend on indivials or teams, but through a process called "mining". By solving the problem of cryptography, people get the right to create new blocks and get rewards. It can be said that the new bitcoin is proced to reward miners to verify blocks. In the beginning, 50 bitcoins were awarded for each block packed. Nakamoto designed a set of rules. For every 210000 blocks excavated (about four years), the reward will be halved. This is what we call "halving" event
the first half was at the end of 2012, when 50 bitcoins were awarded to the 210000 block, but only 25 bitcoins were awarded to the 210001 block
the second half took place in the middle of 2016, and the reward was halved again, so 12.5 bitcoins were awarded in 420001 block
and so on...
until around 2140, 21 million bitcoins were g up, and then they stopped rewarding
Why do we need this half design? If bitcoin is issued too fast and there is no circulation limit, there will be a large amount of bitcoin in circulation in the market, and it will definitely be greatly devalued. One thing to remember: bitcoin is valuable. First, the number of bitcoins is fixed, that is 21 million; Moreover, through the halving process, inflation in the bitcoin economy can be suppressed
the third halving will take place in May this year. Let's wait and see.

Mining is the use of bitcoin mining machine, which is used to earn bitcoin

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining

< H2 > extended data:

bitcoin mining process:

1. To find the ore pool

to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm

2. Download bitcoin miner (software)

in fact, there are many kinds of this miner, you can go to the official website to download

3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before

4, bitcoin mining start

when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver

4. Take bus NO.48 at Dongfeng overpass or Taixing South Road and get off at decaili. Go ahead to Balitai overpass and turn left. Inside Jingyan building is Balitai new culture square

or you can walk to Jintang Road, take bus no.643 at Hedong stadium and get off at Balitai (Weijin Road). Go ahead and cross the overpass to Jingyan building

8. 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.

however, & quot; Once the complete five wave sequence is in place, theoretically speaking, the market will enter the correction stage& quot; In the world of digital currencies, it is not uncommon for prices to fluctuate by hundreds of dollars.

Analysts said that the reason why bitcoin prices ushered in this upward trend is that investors are optimistic about its prospects
