Where is mining in Africa
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
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
secondly, bitcoin has a perfect derivative route, which can accurately hedge risks. What about a shares? We have to buy up and wait for the harvest
bitoffer offers the strongest bitcoin option and is the best risk hedging tool in the spot
how to use options to hedge the fall risk of spot
for example, the current price of bitcoin is US $10000
if it goes up to US $11000, the spot profit is US $1000
if it goes down to US $9000, the spot loss is US $1000
if you open a put option hedging in bitoffer, the cost is only US $20. If bitcoin goes down from US $10000 to US $9000, the spot loss is US $1000, and the put option profit is US $1000, The two offset each other, your account does not have any loss, this is the charm of hedging
after opening the hedging mechanism, your account will make money if it goes up, and even if it goes down, because the risk has been completely offset.
if it's a sign or other symbol, click "Ctrl + H" directly. In the pop-up "replace" window, fill in the symbol you want to remove in the upper line and leave the blank in the lower line. Click replace all
if it's a fixed symbol displayed ring cell format setting, you need to right-click the cell, select "set cell format" and change it to "general".
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 a bank or an institution such as Alipay. However, through the blockchain technology, bitcoin is the first time for human beings to complete the transfer behavior that can be trusted by both parties without the participation of any intermediary. The guarantee, loan, credit, risk control, equity, income and rating based on blockchain can be realized. The value Internet attribute of blockchain makes all kinds of economic activities run more efficiently. Whether ordinary people in society or economic people, they will be mapped as a "blockchain ID" to form a new moral system, evaluation standards and credit records.
