1. bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. 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 money 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

For example

a 4-sheet R9 280x graphics card miner. About 2.9m
power consumption:

the rated power of each graphics card is about 250W, and slightly overclocking is about 300W. Four graphics cards, 1200W
platform: motherboard, CPU, hard disk, etc., which add up to no more than 200W
display, mining machine is basically no display

the total power is about 1400W. 33.6 degrees a day
if the caption is only for ordinary household desktop computers, it is not easy to calculate, because the key is the power consumption of the graphics card. The power consumption of ordinary graphics card is about 150W. And then add the others according to 200W, a total of 350W. 4.2 degrees a day

4. 1、 There is an oil indicator cover on the top of the instrial lock. Just screw it down and fill oil directly. Then there is an oil indicator window in front. The oil level should not exceed the second oil level line< (1) always refuel


all oil holes on the machine and all rotating parts should be refueled with clean sewing machine oil every 4 hours. Other oils and unclean sewing machine oil should not be used, so as not to affect the service life of the machine
(2) regular maintenance and inspection
it is necessary to keep the parts clean, regularly check whether the temperature and sound of the rotating parts are normal, and repair them immediately if any problems are found, so as to avoid damaging the machine
generally, minor overhaul is concted once a month, and cleaning and major overhaul are concted once a half year. After being put into use for a long time, it should be cleaned and overhauled first
the thickness and use speed of the sewing material should be selected within the specified range, and it should not be overloaded or over speed.

8. First, the display interface should match the interface of the graphics card.
Second, choose the one with good performance.
Third, choose the driver (catalyst) of the graphics card.
grasp these principles
