Virtual currency excavator
Only those whose electricity charges are controlled within 0.3 yuan can mine. At present, the daily income of a bitcoin S9 is about 55 yuan (calculated at 7000 yuan), so 30 is 30 × 55 = about 1650 yuan (210000 yuan)
bitcoin is a kind of universal encrypted electronic currency in the world, and it is completely autonomous by users. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
the concept of bitcoin was first proposed by Nakamoto in 2009. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. 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 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual goods, and they can also use bitcoin to buy real-life goods. On December 11, 2017, bitcoin futures began trading on the Chicago Board of Options Exchange (CBOE). On January 24, 2018, the Bank of Indonesia announced the ban on bitcoin payment
1、 mining principle
at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining
looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:
CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)
mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return
in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes
to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin
Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability
there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises
2. Mine pool
in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance
the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day
3. Cloud computing power
in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative
Mining income and risk mining income can be calculated by the following formula:Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee
if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee
Mining risks are as follows:
< UL >at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle
mining difficulty improvement at present, our machines can meet the market demand

in fact, we can do a lot of fun or valuable things
you can buy a hamburger set meal and an iced coke at McDonald's KFC
you can buy a discount ticket at the cinema to see star wars or transformers
you can come to the Internet bar or game hall to play games. On our side, you can play for an afternoon (nobody cares)
you can buy a bunch of roses or a mouse for the person you like to activate your feelings
of course, a 23 yuan LBTC can also be used to do more meaningful things
if there is a poor child in remote Helan Mountain of Ningxia or Laos who can't afford to pay the tuition fee of tens of yuan, as long as he has a smart phone, downloads the LBTC wallet and registers the LBTC address, other LBTC holders in the world can donate money for him to help her go to school. Lbtc3 seconds to the account, up to 1400 TPS per second, so that children can quickly get tuition
many Filipino maids go to Hong Kong and Japan to work. They live frugally every month and save a meager income. However, the handling charge of cross-border remittance is often as high as 5% - 10%, which makes them very difficult. LBTC can help them achieve this goal. LBTC remittance fee is almost zero, and there is no amount limit
until LBTC, like Alipay and WeChat, is accepted by businessmen all over the world, it is good to make hotel, buy breakfast, rent a car and travel abroad with LBTC. LBTC will make our life extremely convenient.
it is suggested to invest in the spot form of yellow / gold / crude oil. Yellow / gold has always maintained its value, and crude oil as war savings can not go anywhere. Recently, the market has fluctuated a lot. It's still easy to make money.
bitcoin mining machine scam is to make money by leasing or selling mining machines the so-called "mining machine" refers to the computer that installs and runs specific software and algorithms. As we all know, bitcoin can only be obtained through long-term running algorithm of computer, and the total amount is limited. Therefore, some manufacturers have launched specially designed and optimized computer procts, known as "mining machine" in January 2018, a mining computer named "Kodak kashminer" appeared at the international consumer electronics exhibition in Las Vegas, which aroused people's attention. But now critics point out that the mining machine plan is actually a fraud, and the publicity for profit is also false precautions: 1. The general computer configuration of bitcoin household can not meet the requirements of bitcoin miner, so it is difficult to earn the electricity cost of a day 2. If you have to use bitcoin mining machine to dig coins, it is suggested to choose a reliable and legal platform to go more steadily. In the legal platform mining, the daily income can be seen, and a certain amount can be withdrawn
