Free mining for bitcoin and ether

Ethernet mining tutorial

1. Create a new folder on the hard disk, which is better than C: eth. Then all the mining software is stored here

2. Download the following software

1) geth -- select geth win download and unzip

2) ethernet -- download and unzip to the same folder and rename it as "miner"

3) Ethereum wallet -- Download the win Ethereum wallet and unzip it and rename it as "wallet"

install all the software

3 Open the command prompt (click win and R at the same time, or click Start menu and enter CMD). The command prompt is a command line parser that allows you to execute command input software in the operating system

After

, you will have Ethereum wallet. But there is no balance, so next you need to build an ethminer. It's time to minimize your wallet

Mining

2. bitcoin is a kind of cryptocurrency based on decentralization, using peer-to-peer network and consensus initiative, open source, and blockchain as the underlying technology. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. 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 decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

Bitcoin uses SHA-256 encryption algorithm. When mining, it competes with computing power. In order to improve computing power, bitcoin has gone through four stages: CPU mining, GPU mining, FPGA mining and now ASIC mining machine mining, and the degree of specialization is getting higher and higher

Ethereum uses the ethash encryption algorithm. In the process of mining, it needs to read the memory and store the DAG file. Because the bandwidth of each read memory is limited, and the existing computer technology is difficult to have a qualitative breakthrough in this problem, so no matter how to improve the computing efficiency of the computer, the memory read efficiency will not be greatly improved. Therefore, in a sense, Ethereum's ethash encryption algorithm is ASIC resistant.

different encryption algorithms lead to great differences in mining equipment and computing power between bitcoin and Ethereum

at present, bitcoin mining equipment is mainly ASIC mining machine with a very high degree of specialization. The maximum computing power of a single mining machine is 110t / s, and the scale of computing power of the whole network is more than 120eh / s

the main mining equipment of Ethereum is video card miner, and there are very few specialized ASIC miner. On the one hand, the "ASIC resistance" of Ethereum mining algorithm improves the threshold of developing ASIC miner. On the other hand, after Ethereum is upgraded to 2.0, the consensus mechanism will be transformed into POS, and the miner can not continue mining

compared with the ASIC miner, the graphics card miner has two orders of magnitude difference in computing power. At present, the computing power of mainstream graphics card miner (8 cards) is about 420mh / s, and that of Ethereum is about 230th / s.

from the time dimension of the past two years, bitcoin's computing power of the whole network is growing rapidly, while Ethereum's computing power of the whole network is growing relatively slowly

The ASIC mining machine of

bitcoin is monopolized by several major mining machine manufacturers, and miners can only buy it from the market; Although the graphics card miner of Ethereum is also manufactured by a special miner, the miner can buy accessories from the market and assemble them according to his own demand

Bitcoin is mined in units called "blocks.". At the time of writing, the reward for completing a block is 12.5 bitcoin. In February 2019, the price of bitcoin is about $3500 per bitcoin, which means you will get (12.5 x 3500) = $42000 Refer to bitcoin mining)

as the channel is widely covered, negative interest rates will be passed to consumers through savings accounts that generate negative returns, which will force consumers to find alternatives such as bitcoin

5. At present, it's difficult for ordinary machines to dig, but it's OK for professional machines to dig. Bitcoin is on the rise recently, so it's OK to invest in speculation. however. A few kilos of bitcoin is a big investment and a big risk. Want to play but limited capital can play flow ore, 1kg ore only 2-3 yuan, enough to play.

6. First, the most common mining method: Hardware mining
Second, the mining method of sin in music: mobile phone software mining
Third, the latest mining method, trading is mining, lock is mining.

7. Making money with low-cost electricity resources

8. There is no windows version
blue whale smart cloud community version v3.1 requires the operating system to use CentOS 7 or above, and can use Yum for installation services.
