Second hand BTC miner

1. This depends on what configuration of bitcoin mining machine you buy. Take Avalon mining machine as an example, avalon2
1t package (10 single-mode groups): the price is 13999 yuan; The price of avalon2 single-mode 100g is 1599 yuan; The price of Avalon 2-generation Miner 2 mole 200g is 2500 yuan. At present, Avalon three generation chips have been released, and Avalon 3 mining machine is about to enter the market.

2. Now the mining machine is generally not big, and the computer host should be smaller. Mining needs to be added to a mine pool, which cannot be g by itself. Now mining has been close to or even more than the currency price, if the electricity charge is free, you can go to mining. Mining power is very large, and you need to install refrigeration equipment. The noise is also very loud. You should also pay attention to this. The noise of the miner of ants is relatively small. The ant miner is OK. If you buy a miner, don't buy a second-hand miner. It's not worth it. The miner's update speed is amazing. If you don't understand, please send me a private letter.

3. Smart people will choose to refit mining machine for other purposes, or put it at home as a souvenir, which is also good.

4. It's too crooked to use

5. To buy a second-hand miner, you need to find a previous miner or a big miner. But second hand mining profit is almost impossible, buy is a pile of scrap metal, to be prepared.

Although the price of bitcoin has suffered a sharp drop before the Spring Festival, there are still some people who are obsessed with "mining". Therefore, mining equipment has become a hot spot, and some people have made a fortune

analysts from Bernstein, a well-known US investment bank, estimate that in 2017, the operating profit of a Chinese start-up company named bitmain in China may reach US $3 billion (about RMB 19 billion) to US $4 billion (about RMB 25.3 billion), which is equivalent to that of chip giant NVIDIA

However, it took bitmainland only four years to achieve such a high profit in one year, while NVIDIA spent 24 years

bitmainland's operating profit may exceed US $3 billion

according to the conservative expectations of 75% gross profit margin and 65% operating profit margin, bitmainland's operating profit in 2017 is US $3 billion to US $4 billion, while NVIDIA's operating profit in the same period is US $3 billion. In a report released on Wednesday, Bernstein analysts said it took bitmainland only four years to achieve this goal, while NVIDIA took 24 years

According to Bernstein's report, each of the antminer bitcoin mining devices currently sold by bitmainland is worth hundreds to thousands of dollars. In addition, the company operates "mining pools" that allow participants to collaborate on bitcoin mining to rece costs. Bernstein estimates that bitmainland has 70% to 80% market share in bitcoin miners and ASICs

according to the daily economic news, the ethash algorithm currently used by Ethernet is based on the demand of graphics chip, which is suitable for PC mining, and the mining machine is not good at it. The market expects that bitmainland will soon launch a new mining machine with low energy consumption and high efficiency. A professional mining machine can be equivalent to several 8-graphics card mining machines. After the official launch, it is bound to impact the original PC mining market with graphics chips. At that time, because of "mining" and soaring chip prices are also expected to return to rationality

Mitch Steves, an analyst at RBC Capital, believes that the price of Ethernet currency has skyrocketed from $10 in early 2017 to $1000 now, and the possibility of exclusive mining chips is much higher than a year ago. Steves also pointed out that if bitmainland really sells chips dedicated to Ethernet coins, the mining efficiency will be far better than that of graphics chips, and at that time, it will take away the business of NVIDIA and AMD

according to the daily economic news, NVIDIA's financial report for the fourth quarter of 2017 released in early February found that the company's data center, including the sales of graphics processing units (GPU and graphics card), had an operating revenue of US $606 million in the fourth quarter, making it the second largest revenue source of NVIDIA. The chief financial officer of NVIDIA also mentioned that in terms of the overall demand for NVIDIA procts, the contribution of digital money market is difficult to quantify, but I believe the percentage contribution in the fourth quarter is higher than that in the previous quarter

7. At present, the mainstream price of Avalon mining machine in the market is as follows:
Avalon 2 generation single-mode group 105g
:
￥ 488
3 generation single-mode group 290g:
￥ 2088
3 generation single-mode group 245g:
￥ 1758
3 generation whole machine 800g:
￥ 7866
I hope I can help you.

9. It's a garbage collector or a miner. If it's a miner, save it. Don't do too much. Now the cost of mining is very high, which is close to or even more than bitcoin. Retail mining has graally withdrawn from the historical stage of bitcoin mining. Now mining relies on low energy consumption and low electricity price. This bitcoin home network has related analysis articles.

10. It's suggested that indivials don't need to buy mining machines alone. Now the team is fighting. You can go to celletf and have a pledge to mine. It's not bad to make a steady profit every year
