1. < UL >

this is mainly e to the 51% attack, because before some of the world's well-known mines, e to the low rate and convenient use, many miners went to those large mines to mine. As a result, the computing power of the mines soared, approaching or even exceeding 51% of the global computing power many times

bitcoin community has also raised a big discussion about 51% attack for many times,. The mine pool operators also called on the miners to move to other mines in a responsible manner, and finally 51% of the attacks were solved. Many of China's miners have moved to fish ponds

most of the new miners have joined the fish pond because they don't know about the global mine ponds, and many of the previous mines have died e to poor management

2. In terms of physical fitness and material stacking, a-card is still resistant to operation, and double precision is also high in a-card, so mining efficiency is high, and a-card will be selected for basic mining

3. Comparison of two ant double blade mining machines in btcguild and f2pool mining pool (personal test for reference only)

1. Machine: two ant double blade mining machines (rated speed: 180gh / s, rated power consumption: about 360W)
2. Network: ordinary family 8m broadband connection
3. Test time: from 11:00 p.m. on January 27 to 7:00 a.m. on January 28, 2014, a total of 8 hours
4 Comparison:
a miner in btcguild (EU stratum. Btcguild com:3333
the average speed of 8 hours is 175.92gh/s, and the profit is 0.01424974
one miner operates in f2pool (stratum)+ tcp://stratum.f2pool.com : 3333)
8 hours average speed 180gh / s, revenue 0.01230566
5 The test results are expected (the theoretical value under the difficulty of the day does not consider other factors):
the profit of an ant double blade miner in btcguild mine is 0.00194408 more than that in f2pool mine in 8 hours, 0.00024301 more per hour, 0.00583224 more in 1 day (24 hours), and 0.1749672 more in each month (30 days)

4. Choose projects with high return rate and short return cycle

5. Fish pond f2pool is the earliest mine pond in China. It was closed for a period of time e to poor management, probably in July last year, but it was opened again soon. They are not only mining pools, but also mining machines. Shenyu mining machine failed because of the chip problem. In 2015, we set up a Wright coin miner and crowdfunding
there has been no major safety accident in the fishpond f2pool. In addition, 51% of the problems often occur in large foreign mines, which also gives the fishpond f2pool opportunities for rapid development. They are all people in the circle, and they also work as information websites and have a wide range of contacts.

6. For example, when you connect an object with a 5-meter line and pull the object to the level of the line, it is increased by 5 meters
G is 10, from S = 0.5gt & sup2; T = 1 second
V = 10 × 1 = 10
then f = MV
if the required impulse is 500kN
m = 500000 can be obtained ÷ 10 = 50000kg
is 50 tons,

if the line is longer, it can be pulled higher and the weight needed can be lighter
