It is reported that the performance of bm1385 chip is more than twice that of bm1384
The power supply scheme of S7 is similar to that of S5. The S5 + mode of dense chip arrangement is adopted, which makes the arrangement structure more compact. Under the same space, 60 chips are placed in S5 and 162 chips are placed in S7 The price of S7 is 1823 US dollars, equivalent to 11650 RMB yuan, and the delivery time is from September 21 to September 30. At the same time, the official announced the parameters of ant mining machine S7. The chip adopts bm1385, a 28nm fully customized chip independently developed by bitcontinental, with a computing power of 4.86t and a power consumption of 1201w. Ant miner S7 is the best miner with the best power consumption ratio so far, and the power per T is about 250Wofficial website is not open for sale at the moment. Users of early adopters can place their orders in overseas official website. The delivery address is 17% of the Chinese mainland tax and the purchase price is 13630 yuan. p>

In China, IPFs has been fermenting for three years, but the actual preaching cycle is far more than three years. In these three years, the final display of mining technology is in the test network and space race, and more importantly, the formal excavation after the main network goes online. Interstellar Infinity has been leading the instry in terms of computing power ranking and single-T mining efficiency, especially the single-T mining efficiency, which remains at the top level in the field of IPFs distributed storage
180 coins
invest 200 coins, 230 coins can be settled in a round of two months, 1380-1200 = 180 coins can be settled in six rounds of a year, and 200 coins can be g in 52.5 days to rent a miner
you can rent one in 44.5 days for the second one, 29 days for the third one, 21 days for the fourth one, 13.5 days for the fifth one, 5.5 days for the sixth one, and you can pay 200 yuan for two for the seventh one
extended data
using time superposition 153.5 days to earn 200 coins, two medium-sized mining machines run in parallel, the next 26.5 days can settle 200 coins, three medium-sized mining machines run in parallel. In the next 17.5 days, 200 yuan can be settled, and in 8.5 days, six small mines and eight minicomputers can be fully loaded, with a total of 208 days
for the remaining five months, the net income will be 126.8 yuan according to three rounds of calculation (126.8 yuan for four small mines and eight minicomputers) × 3 = 380.4 coins
mining machinery seed 936 + 380.4 = 1316.4 coins, a year later, the most conservative estimate of the value of a coin is 700 one coin
700 × 1316.4＝921480

the main engine has turned away my youth, the windlass has broken my dream, the generator can't send out the spark of love, the high frequency can't shout out the beautiful hope, the radar can't scan the coordinates of the beautiful woman, the satellite guide can't measure the course of my heart, the depth sounder can't measure how deep my love for you, the cable can't pull back the fall and frivolity, and the touch pad can't offset the punishment of impulse, The fire extinguisher can't extinguish this wishful thinking

secondly, for some purposes, the validity period is regarded as one year or half a year. For example, to buy a train student ticket, it needs to be sealed by the school's academic affairs office every half a year or once a year before it can be regarded as a valid certificate
finally, in some special cases, the total validity period of the student ID card will change, but it is consistent with the period of study. Special cases include: being expelled, being dissuaded from school, voluntarily dropping out of school, delaying graation, etc
