Recently, the bitcoin mining machine and graphics card mining machine market are also extremely out of stock. Many mine owners may not be able to buy mining machines at higher prices, but they are valuable now and have no market.
Recently, a friend and a big boss, the general agent of graphics cards in China, are engaged in graphics card mining machines. I have worked with him on some graphics card mining machines before, and I have also hosted several bitcoin mining machines in Jinwei. I know a little about mining machines, and I just calculated the cost performance and cost cycle of these two kinds of mining machines for my friends these two days. Let's do the input-output analysis of these two kinds of mining machines.
The following is the comparison between ant mining machine and MSI RX 470 8 card graphic mining machine.
First, the basic concepts related to mining.
1, what is mining:
Mining is actually accounting by mathematical calculation, and at the same time using a lot of encryption operations to ensure that this account book will not be tampered with. Mining is the production and distribution process of encrypted currency, and at the same time, the calculation ability and electricity expenditure are used to ensure that the distributed account books cannot be tampered with. It can be simply understood as the process of selling the computing power of our machines in exchange for the corresponding digital currency return.
2, what is a mining machine:
The bitcoin mining machine and graphics card mining machine introduced in this paper can be understood as a computer with many high-performance CPU chips and graphics cards. Similarly, the graphics card mining machine also needs basic accessories such as cpu, memory, motherboard, hard disk and power supply.
3. What coins can I dig?
Ant S9 mining machine digs bitcoin; The graphics card mining machine can dig Ethereum (the graphics card mining machine can dig Ethereum ETH, Ethereum Classic, etc., zero coin ZCash, Monroe coin Monero, etc.). ), and this is just an example of Ethereum. )
Second, the calculation of mining income
1, ant S9 mining machine
It is a bitcoin mining machine with high computing power and high mass production on the market, but it is still hard to find a machine. The spot price is 30,000 RMB, and the official price is about 23,000 RMB. Futures should be arranged in April and May.
Computational force:13.5s/s
Power: 1350W
Mining machine price: 30,000 yuan
Electricity charge: 0.5 yuan/kWh
65438+ 10 month 13 Japanese currency price 100000 RMB
The following results are calculated by the calculator of the mining website:
Income and payback period:
Current daily income: 199
Daily electricity charge: 16.2
Daily net profit: 183
Days of return: 164 days (about 5.5 months)
Summary: The current cost of Ant s9 mining machine is 30,000 yuan, and the payback period is about 5.5 months, so the machine does not have the function of preserving value.
2. RX470 8 card graphic mining machine
Now the graphics card mining machines are all the same, and many graphics cards suitable for mining are hard to find. Take the graphics card general agent as an example. In his own words, selling mining machines is not as good as making much money by mining, and he can't get many mining machines himself, not to mention the high demand of the whole market.
Configuration of graphics card mining machine, taking 470 8 card mining machine as an example:
Income and payback period:
Final force 224M
Power 1600W
The price of mining machine is 29,000 RMB.
Electricity 0.5 yuan/kW
65438+ 10 month 13 Japanese yen price is 9500 RMB.
Income and payback period:
Current daily income: 280.9
Daily electricity charge: 19.2
Daily net profit: 26 1.7
Return days: 1 10.8 days (about 3.7 months)
Summary: At the cost of 29,000 yuan for 8 cards of 470 mining machine and the current currency price, the payback period is probably less than 4 months. And after one year, the graphics card can be sold at least at a depreciation price of 50%.
Video card mining machine real shot:
Summary of regression cycle: the ant S9 is 5.5 months; The graphics card mining machine is 3.7 months old, and the graphics card mining machine also has depreciation and preservation.
The above is only based on the comparison between the current prices of Bitcoin and Ethereum and the prices of mining machines. At present, there are uncertain risks in buying coins and mining, but the risk of mining is relatively lower than that of speculating coins, but the yield is relatively stable.
Mining still has certain risks. Mining machine prices and electricity charges are fixed inputs, while currency prices fluctuate constantly. The biggest risk is that the currency price will drop and the computing power will increase greatly. If the price of money is halved due to market reasons, or the computing power is gradually enhanced due to the participation of more and more players, personal income expectation will be greatly extended or income will be less and less.
If you can buy a mining machine, mine it at a lower cost, and recover the cost of the mining machine as soon as possible, you can make a stable profit in the later period. Mining can also be understood as fixed investment. There are coins that can be mined and sold at an ideal price to obtain a higher return on investment; If someone digs, sell it and put it directly in the bag.
It is suggested that you invest appropriately within the controllable risk range, try a little first, and then gradually increase the number of machines to control the risk reasonably. Investment is now considered hedging.
