When did bitcoin dig
bitcoin is the first distributed virtual currency
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
extended information:
as a virtual commodity, bitcoin itself has no national boundaries, and its operation mode is a "decentralized" monetary system, which is very convenient for one-time large transaction. Bitcoin is traded through the network, and the owner's identity is only in the form of a set of encrypted computer code
in the operation, input a digital address directly, click the mouse a few times, and wait for the confirmation of the transaction to complete the transaction. The network can only record which address a bitcoin was g up from and how it was transferred
however, the identity of the owners of these addresses can not be verified, which is just like when money goes to an ownerless bank account, the relevant transactions can easily be invisible from the perspective of government supervision, and it is difficult to be tracked or intercepted. In addition, bitcoin can evade the scrutiny of exchange control institutions required by normal cross-border remittance, and the transaction records will not be recorded by banks and other parties
naturally, the problem of reporting to relevant departments after the transaction exceeds a certain amount is avoided. Buy bitcoin with domestic currency, sell it on foreign trading platforms, and withdraw it in US dollars. Asset transfer can be completed in a few minutes
it is not difficult to open an overseas bank account related to bitcoin for foreign exchange, and the conversion is very convenient. Because of these characteristics, bitcoin has been chosen by criminal organizations
in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

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.
Bitcoin is a kind of network virtual currency. 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. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

a total of 2100W bitcoins are issued, and each block is generated for 10 minutes, and a block rewards a certain number of bitcoins. In the beginning, 50 bitcoins were awarded for each block of mining. In the future, the reward was halved for every 21000 blocks (about once every four years). Now, 12.5 bitcoins are awarded for each block generated. The generation time of each block is 10 minutes, but with the development of computer technology, now the mining calculation power is increasing, so the generation time of a block must be less than 10 minutes, which requires certain control measures to ensure this time. This measure is the difficulty of mining. If the output time of each block is less than 10 minutes, the difficulty of mining will be increased. If the output time is more than 10 minutes, the difficulty of mining will be reced. The difficulty adjustment time is 2016 blocks, that is, 2 weeks
after every 2016 blocks, all nodes will automatically adjust the mining difficulty according to a certain formula. This formula is obtained by comparing the latest time spent in 2016 blocks in this cycle with the expected time (20160 minutes, i.e. two weeks)
new difficulty = old difficulty * (time spent in the past 2016 blocks / 20160 minutes)
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
