SKU mining is real or not
Online mining is real, that is, traffic mining
because those who come in after mobile phone mining will be cut leeks
precautions:
1. In the past two years, various myths about blockchain "overnight wealth" have been constantly staged, and "mining" cryptocurrency has become a new trend of wealth, and mobile phone mining is becoming more and more popular
2. There will be special mining machines for real mining. After all, every mining machine is not cheap now. Mobile phone automatic mining can be obtained at a very low price. What you dig is not bitcoin. Basically, the counterfeit coin you send is not worth money. At that time, you will still be cut leeks
mining is also not desirable
unless you're a tech savvy bitcoin digger
however, bitcoin will be obtained through other channels
in addition, indivials are not recommended to hold currencies other than bitcoin.
bitcoin mining machine scam is to make money by leasing or selling mining machines
the so-called "mining machine" refers to the computer that installs and runs specific software and algorithms. As we all know, bitcoin can only be obtained through long-term running algorithm of computer, and the total amount is limited. Therefore, some manufacturers have launched specially designed and optimized computer procts, known as "mining machine"
in January 2018, a mining computer named "Kodak kashminer" appeared at the international consumer electronics exhibition in Las Vegas, which aroused people's attention. But now critics point out that the mining machine plan is actually a fraud, and the publicity for profit is also false
precautions:
1. The general computer configuration of bitcoin household can not meet the requirements of bitcoin miner, so it is difficult to earn the electricity cost of a day
2. If you have to use bitcoin mining machine to dig coins, it is suggested to choose a reliable and legal platform to go more steadily. In the legal platform mining, the daily income can be seen, and a certain amount can be withdrawn
The highest speed used in vehicles should be the engine of F1. There are about 900 moving parts in the engine of an F1 racing car, and its maximum speed can exceed 19000 rpm, while the maximum speed of an ordinary car engine usually does not exceed 8000 rpm
when the engine of F1 racing car runs at the highest speed, the spark plug ignites 150 times per second, the piston reciprocates 300 times, and the acceleration is as high as 8500g
However, the mass ofengine will not exceed 100kg, while that of ordinary 1600cc engine will exceed 120kg. But now because the limit is 19000, if there is no limit, it can reach 22000
< H2 > extended data:
the advantages of diesel engine are high torque and good economic performance. Each working cycle of diesel engine also experiences four strokes: intake, compression, work and exhaust
However, since diesel fuel is used in diesel engine, its viscosity is higher than that of gasoline, so it is not easy to evaporate, and its spontaneous combustion temperature is lower than that of gasoline, so the formation and ignition mode of combustible mixture are different from that of gasoline engine The main difference is that the mixture in the cylinder of diesel engine is compression ignition, not ignition. When the diesel engine works, air enters the cylinder. When the air in the cylinder is compressed to the end point, the temperature can reach 500-700 ℃, and the pressure can reach 40-50 atmospheres
