Bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (a blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, which contains all transactions in the bitcoin network) .
Bitcoin miners manage the bitcoin network by solving the problem of workload proof mechanism with certain workload - confirming transactions and preventing double payment. Because hash operation is irreversible, it is very difficult to find the random adjustment number of matching requirements, which requires a continuous trial and error process that can predict the total number of times. At this time, the workload proof mechanism will play a role. When a node finds the solution of matching requirements, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it matches the rule. If other nodes find that they really meet the requirements (the operation target required by bitcoin) by calculating the hash value, then the data block is valid, and other nodes will accept the data block
Nakamoto compares the generation of bitcoin by consuming the power and time of CPU to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer 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. Each bitcoin node 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 tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target

Indications before purchase
Please never forget that regardless of the current performance of miners, mining remains a risky activity.
Like any type of investment, never invest more than you can afford to lose.
The price of miners can vary from day to day depending on market behaviour.
Abstract: We compare and measure various performance metrics for two of the latest and most energy efficient Bitcoin mining products, MicroBT’s Whatsminer M30S+ and Bitmain’s Antminer S19 Pro. Obviously the more expensive 7nm Bitmain product is more powerful, however the miners are pretty similar in terms of output. Our data over a short three day period shows that the Bitmain miner has slightly stronger performance than the Whatsminer, however the Whatsminer appears to have superior stability. In general, both machines are impressive and we predict the two companies will be in neck and neck competition over the next few years.

1. How can I trust you?
A: We can do Escrow for you as long as you willing to pay the transaction fee.
2. If my miners dont work, what can I do?
A: All miners will be tested before shipping out. We will teamview and help you to solve the problem for programing issues. For large quantity, we will provide back up accesorries, like control board, hashboard for you to replace right away. More discounts can be negotiated.
3. Is mining still profitable?
A: Hard to say.
4. What models is the best?
A: It depends. Your electricity cost, your budget, and how you know the market etc are elements for you to consider.
