How long does it take for a normal mining card to dig a bitcoin
CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining
while mining chips are updated, The change of mining speed is:
CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5thash / s) → large scale cluster mining (3.5thash / s * x)
mining speed, which is called computing power in professional terms, 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
in order to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. They have to guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin
so far, the highest 1btc price in bitcoin history is about $20000, with a market value of more than $60 billion.
Step 1: prepare mining machines and pools
if you want to dig bitcoin, you must prepare professional equipment. At present, there are many professional mining machines on the market, and the pool is also essential. When you choose a pool, you should also compare the output and income gap of each pool, and then choose the most suitable one
Step 2: register and set the mine account
after the mine is ready, register the mine account and set a common email. When setting the mine account, each CPU or GPU needs to set a mine account
Step 3: download the bitcoin miner
after you register and set up your account, you need to download the bitcoin miner. When downloading the miner, be sure to choose the miner that can make your CPU and graphics card play the most function. After downloading, set the server, user name, password, device and so on
Step 4: Mining
after setting up the miner, click the "start mining" button, the miner will enter the state of full speed operation, and the miner will start mining automatically.

first of all, bitcoin is not created one by one. Bitcoin is made up of one account book after another. As long as you can record one account book, the system will reward you accordingly (starting from 2009, after four years, one will reward 50 bitcoins, another four years, one will reward 25 bitcoins, and so on), Because the account book records the transaction information, the transaction fees generated by the transaction also belong to the bookkeeper. Such a good thing, of course, everyone wants to keep accounts. At this time, the more wonderful thing will come. The system will put a mathematical problem every ten minutes. Whoever works out first will have the right to keep accounts. They can keep accounts and get bitcoin generated by keeping accounts
then the generated bitcoin will be saved in your wallet address. You can transfer the bitcoin in the address to EXX. There are not only bitcoin, but also more valuable currencies. Of course, you need to choose
investment is risky, and we should cherish it
It's a fraud. It's a 100% online pyramid scheme
The reasons are as follows:-
RMB recharge purchase π First, according to the exchange rate (RMB 6.74 to US $1 on July 26, 2017), it will be converted into US dollars, and then it will be purchased at the rate of US $5.98 on July 28, 2017 π Purchase π In the process of recharging, the handling fee is charged in US dollars
the handling charge is still very high (they say it's 6% of the total). You can transfer the funds π In this "yu'ebao", 10 days of appreciation will not bring back the money of handling charges< br /> π It's expensive to buy coins on the app's exchange (5.98 U.S. dollars to 1 π 97 dollars to 1 π Currency). I just hope you put the money in it and don't withdraw it, waiting for appreciation and occupying your money. As long as it turns into RMB, it will be sold and it will lose money
-
this π Currency is not the currency issued by the state in the form of economy (equivalent to gold or monetary credit of the State Finance), but the virtual value issued by a certain group, which will have risks. You only need a mobile phone number to register, not an ID card. It means that it is not a national act, and the currency value will have the risk of cashing and cashing
in other words, if the app is banned or closed by the competent department of the national government, there will be no virtual currency purchased with RMB recharged by itself. So it's a scam
According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts
extended data
unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
bitcoin = RMB = US dollar, so everyone went to mine
virtual currency ensures the security of currency through close and complex mathematical calculation, and the more people join in mining, the safer the currency will be
mining needs calculation, and calculation needs graphics card. Ordinary graphics card can draw pictures, calculate, play games, etc. professional mining card sacrifices other functions besides calculation, and is dedicated to mining
Mining cards are generally used in professional mining machines, such as
coin potential
mining machine, which is tens of times faster than ordinary computer mining machine, and its computing power is up to 165mh / s. High computing power means that your mining speed is fast and your income is high, so now mining has entered the era of specialization and clustering. If you want to mine, you must buy mining machines and join the mining pool, otherwise the mining income is not enough to pay the electricity bill
it's almost impossible for ordinary computers to find virtual currency, because the proction of currency is a competitive mechanism. The computing power of ordinary computers is almost the same as that of professional mining machines. If you really want to calculate, your computer can't dig bitcoin. If you dig ether currency, the monthly income is 353 yuan, and the machine needs to be turned on 24 hours.
