Computing power of chrysanthemum USB minicomputer

1. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.

2. The stability of chrysanthemum mining machine has been improved a lot, OK? Although prices are falling, objectively speaking, compared with graphics cards, gridseed's Chrysanthemum miner is more cost-effective. In addition to the price, you also have to consider the computing power, power consumption and other factors. The graphics card failed completely.

3. According to the results of bitcoin mining income calculator on bitfan website:

income: 0.0009 BTC RMB & # 165; 3.09 US $0.50 (at present, the price of bitcoin is about 3600 US dollars, about 580 US dollars, and the mining difficulty is 18736441558)

the mining speed changes at any time according to the mining difficulty

this kind of Power Miner is only for those miners who want to experience mining. In addition to electricity and other costs, there is basically no profit. If you want to get more profit from mining, you have to buy more power miner

for example, the mainstream miner Avalon 290g single-mode miner in the market, you can choose to buy the T-class package.

4. Caiyunbit's original creation is endless

unknowingly, it came to 2014, with several Avalon generation USB mining machines in hand. You're right. It's not a roasted cat USB miner or any other chip. It's a USB miner of Avalon generation, with a single computing power of about 300m. Of course, the USB mining machine with more than 300 m computing power is of little practical value. It's just a souvenir for everyone<

first, the appearance
first, let's look at the appearance. The workmanship is regular, not exquisite, but slightly rough:

Second, the required software
let's start running cgminer to see how to use it in practice. Before starting work, you need to download three softwares:
1. Cgminer. Anyway, the latest version of 3.9.0 is also available for testing, http://ck.kolivas.org/apps/cgminer/
2. Zadig. This software is needed to replace the driver later. Download it from the same directory as cgminer

3. USB driver of mining machine, http://www.silabs.com/procts/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

3. Install and run

after downloading the above software, start to install and run
1. Insert the USB miner first, and you will be prompted to find the new hardware, and then complete the driver installation according to the prompts

2. After the driver is installed, you can see the new things in the device manager

3. Run Zadig, first click options -- list all devices, then drop down to select port, and replace the driver silabser (v6.6.1.0) with the driver WinUsb (v6.1.7600.16385) recognized by cgminer. After this step is completed, it is recommended to restart the computer

4. Create a new batch file in the cgminer directory, The following command: cgminer - O pool address - U miner name - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: number of mining machines
there are six USB mining machine fish pools, for example: cgminer - O stratum+ tcp://stratum.f2pool.com : 3333 - U AAAA. 2 - P 123456 -- Icarus options 115200:1:1 -- Icarus timing 3.0 = 100 -- USB: 6
since cgminer3.2.0, The method of supporting USB mining machine is modified, which does not need to add the - S - com parameter

5, run batch processing, and start to display mining data, about 300m, which is basically normal.

5. The miner is not set right. Give me your contact information. I'll help you remotely

6. According to the results of bitcoin mining income calculator on bitfan website:
income: 0.0009

RMB & # 165; 3.09
US $0.50
(at present, the price of bitcoin is about 3600 US dollars, about 580 US dollars, and the difficulty of mining is 18736441558)
the speed of mining changes at any time according to the difficulty of mining

7. In fact, bitcoin mining can not blindly pursue the size of computing power, but also depends on the overall performance of the miner. For example, the single-mode group of Avalon mining machine 2 will be able to recover its cost in about 40 days, but the 800g recovery time of Avalon mining machine 3 is far away, unless the currency price rises. If you are a retail investor, it is suggested that you buy mining machines with small calculation power and fast cost recovery time, which should be regarded as playing. If you have abundant funds and the ability to set up large-scale mining plants, it is suggested that you buy mining machines with high calculation power and high profits. Avalon's 2.3t miner is said to be coming soon.

8. Illegal fund-raising refers to the behavior that an entity or indivial raises funds from the public by issuing stocks, bonds, lotteries, investment fund securities or other creditor's rights certificates without the approval of relevant departments in accordance with legal proceres, and promises to repay the principal and interest or give returns to the investors in currency, material object or other ways within a certain period of time
the crime of financial fraud refers to the act of defrauding public or private property or the credit of financial institutions and damaging the order of financial management by making up facts or concealing the truth for the purpose of illegal possession.
