Rejection rate of BTC mining machine
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
1. Machine cost: the cost of purchasing mining machine
2. Power cost: the power cost consumed by machine mining
3. Auxiliary costs: personnel maintenance, network, cable consumables, heat dissipation, etc.
for a simple example, take the mining machine of ant S9, which consumes less power on the market, for example, the calculation power is 13.5T, and the power consumption is 1400W
when the mining machine runs for 24 hours: 1.4kw * 24 = 33.6 degrees
Shenma m3, which consumes more power on the market, has a calculation power of 11.5t, The power consumption is 2150w
under 24-hour operation, the power consumption of a single machine is 2.15kw * 24 = 51.6oc
which is roughly equivalent to the power consumption of energy-saving air conditioning, but the bitcoin miner needs 24-hour uninterrupted operation, the power consumption of a single machine is very large after a year's calculation, and the step price cost of household electricity is too high, When the market is not good, the income may not be enough for the electricity expenditure, so at present, mining will choose to be hosted in the mine, which can get cheap electricity and rece the cost price of mining. The price below 30% is the ideal price, which can keep the price of bitcoin falling to a low level, and there is still some income< According to the current mining difficulty of bitcoin:
BTC revenue per ton: 1th / s * 24h = 0.00007087btc
calculated by the comprehensive 12t machine computing power, the daily output is:
0.00007087t * 12t = 0.00085044btc
then the time required for a single machine to dig a BTC:
1 / 0.00085044 = 1175 days
the time required for ten mining machines to dig a BTC:
1 / 0.0085044 = 117 days
100 days In other words, according to the current difficulty, it takes about three years for a single miner to proce a bitcoin, 3.9 months for ten miners to dig a bitcoin, and 11.7 days for a hundred miners to dig a bitcoin. The cost of a single miner is about 8500, Ten are around 85000, one hundred is 850000, less than one million, and one month's income is more than two bitcoins. According to the current price of bitcoin, the price is about 120000. So, although the income of bitcoin mining is not as good as before, it is still considerable compared with other investment projects
however, these benefits do not include decting the cost of electricity charges and later maintenance of machines, so the premise of mining is to find a mine with low electricity charges. If the quantity is large, we need to find a safe, reliable and stable mine. What's more, we need cheap electricity to lower the cost price.

You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated 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 in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
however, you really regard mining as fun and entertainment. If you don't care much about whether you can dig, you can also let your own machine dig all the time. However, the machine configuration above you should not be low, but it is not suitable for mining, just as the swimming champion is not necessarily good at mountain climbing
generally speaking, mining machines mainly focus on graphics cards, which have little to do with processors, main memory boards and hard disks. Of course, they need to be stable and not crash for a long time. In fact, a card is more suitable for mining. In principle, you can go to the network. It is said that before the emergence of R-Series a card, the card with good mining effect was not hd88708750, But we despise the old graphics card that has been eliminated
No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law
extended information:
{rrrrrrr}
transaction mode
bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet
after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions
