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 a lot of people are speculating money and buying mining machines to dig crazily, so the price is not cheap. Basically, it's about 20000-40000. Recommend a digging chain network, which introces the configuration of mining machine and all kinds of information, you can understand it. Just ask for an ace ē
3. Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data
mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
4. 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.
5. Thousands to tens of thousands, depending on which one you choose!
6. This depends on what configuration of bitcoin mining machine you buy. Take Avalon mining machine as an example, avalon21t set (10 single-mode sets): 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.
7. Don't use computers to mine, the money you earn is not enough for electricity
8. The single price of this mining machine, you want to see where you buy it? And there are some websites that are very cheap, but there are some websites, especially Jingdong. These retail websites are very expensive, very expensive, very expensive
9. This is a rudimentary remnant camera. It's enough to take souvenir photos! If you really like photography, or you are a fan. It's better not to buy this camera.
10. I don't know what kind of business your company does, shopping mall, Dazhong supermarket, standard supermarket or convenience store? 300000 is too little! The monthly sales volume of a standard super store is more than that. Where can I use a distribution center? In addition to sales, it also depends on the number of stores. Generally, about five stores can be considered, and more than ten stores are very necessary. But with the distribution center, there will be an extra expense, so cost accounting should be considered. The distribution expense should be included in the store operating cost. Building a distribution center is the same as opening a store. It is built from scratch and from small to large. According to the size of the company, we should consider the sales volume of the company and the cooperation mode of suppliers to determine the size of the site and the number of personnel. As for the system and process, we can generally find senior friends in the instry. The internal operation of the distribution center is very different. According to the actual situation of your company, improper operation will bring great trouble to cross department cooperation, increase the cost, and increase the shortage of stores e to non supplier reasons, thus affecting sales
