How about hongniu mine

1.

Mine pool refers to:

as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by the bitcoin network on the bitcoin network

after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly, and the website established in this way is called "mine pool"

extended data:

the existence of the mine pool reces the difficulty of bitcoin and other virtual digital currency mining, reces the mining threshold, and truly realizes the bitcoin mining concept that everyone can participate in

but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have huge computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks against virtual digital currencies such as bitcoin, The consequences are very terrible:

the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network

5. The probability of being taxed is very high. Generally, the tax rate of 3C procts such as computers is 10% - 20%. It can be transshipped, but it's better to find the right transshipment company. Encountered some unreliable transshipment company lost, or damaged on the trouble. Moreover, some transshipment companies do not transship more than 1000 US dollars, so they should ask hello in advance. You can also directly look for deposits in the United States, which also saves time and worry.

7. When the diameter of the hole is less than 5 mm, the manual feed is generally used, and the small bit of 3-5 mm is selected. The feed rate of ordinary twist drill can be calculated according to the empirical formula F = (0.01 ~ 0.02d0). When processing cast iron and nonferrous metal materials, the feed rate f can be 0.15-0.50 mm / R; When machining steel parts, the feed rate f can be 0.10 ~ 0.35 mm / R. If advanced drilling and grinding methods are adopted, the axial force can be effectively reced and the feed rate can be increased.
