How to judge the number of people digging this coin by calculati

21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day

since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining

as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation

Bitmine is real

bitcoin is proced by mining. Every 10 minutes, the miners of the whole network work out an arithmetic problem together. Whoever works out the answer first is equivalent to digging into this block, and the miner can get the bitcoin reward of system rebirth

after bitcoin is g in the mine, the income is distributed according to the proportion of the mine's computing power, so as to ensure a more stable input-output

every other time point, bitcoin system will generate a random code on the system node. All computers in the Internet can search for this code. Whoever finds this code will generate a block and then get a bitcoin. This process is often called mining. Computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin profits more quickly, which is also an important reason for the recent shortage of graphics cards

It's said that the currency circle has been going on for one day and the stock market has been going on for one year. Although it's a bit exaggerated, it's not unreasonable. In recent days, bitcoin has gone up sharply, but it has come down slightly today. It's estimated that no one can match the speed of the bull bear conversion in the currency circle. However, among many virtual currencies, how can we find high-quality projects? Xiaobian thinks that the bull market is not surprising. The key point is that the bear market still insists on giving weekly reports, at least for the projects with reliable teams. Today Xiaobian still brings you weekly reports of some high-quality projects. The following is the latest weekly project progress report (April 9-April 15, 2018) released by ubtc team. The specific information is as follows:

pre upgrade of Ub smart contract:

smart contract is one of the major milestones of the technology roadmap of bit fed project. In order to prepare for the implementation of smart contract on UB, the UB team made some adjustments on April 10, 2018, as follows:

1. The block speed was adjusted from 10 minutes to 1 minute

2. The difficulty adjustment cycle was once for 10 blocks

3. Block reward was adjusted to 1 ubtc

this adjustment requires users to download the latest version of the wallet to ensure that subsequent use will not be affected

about ubtc:

unitedbitcoin, referred to as UB, code ubtc. UB is not only an upgraded version of bitcoin, but also a leading global blockchain ecosystem. UB is headed by Jeff garzik, a veteran of bitcoin, a core developer of bitcoin and a leader in the blockchain field

UB 100% inherits bitcoin's blockchain and upgrades and optimizes it. The upgrade and optimization of Ub include expanding the block size to 8MB, supporting segwit isolation witness, adding smart contract and lightning network, etc

UB is committed to bringing the inactive bitcoin credit into full play. Finally, based on these credits, we can issue stable currency anchored by legal currency, which can be used in a wide, fast, efficient and intelligent business society

at present, UB team has developed anybit mobile wallet app (anybit is a decentralized multi currency wallet APP), core, core QT and electrum wallet (electrum is a lightweight wallet supporting multi signature), and released a complete blockchain browser

more than 18 trading platforms around the world support ubtc trading

when building bitcoin, Nakamoto wants bitcoin to be a decentralized currency, not only for use and trading, but also for mining. But it backfired. With the increasing value of cryptocurrency such as bitcoin, mining has become an instry. The competition is more and more fierce, and the pursuit of mining computing power is higher and higher. Therefore, from ordinary computer mining, ASIC mining machine and GPU mining machine have evolved

the algorithm of ASIC mining machine is almost sha256, while the algorithm of GPU mining is different. For example, the algorithm of BTG is equihash, and the algorithm of BCD is optimized x13. Although it is not absolute, it can be simply considered that the currency of sha256 algorithm is generally mined by ASIC mining machine. Other algorithms are basically using GPU miner. There are also exceptions. Scrypt's Leyte coin used to be mined by GPU miner, but later scrypt's algorithm was also conquered by ASIC chips, such as ant miner L3 +, which is the ASIC miner used to dig Leyte coin

ASIC miner refers to the miner that uses ASIC chip as the core of computing power. ASIC is the abbreviation of application specific integrated circuit, which is a kind of electronic circuit (chip) specially designed for a specific purpose. Some mining machinery factories have designed ASIC chips specially for computing the sha256 algorithm of bitcoin, and the mining machinery using them is ASIC mining machinery. Because ASIC chip is only built for specific computing, its efficiency can be much higher than that of CPU. For example, the current mainstream ant miner S9 is ASIC miner, which uses 189 ASIC chips, the computing power reaches 13.5th/s, and the power consumption is only 1350W. As a comparison, the computing power of gtx1080ti, the flagship computer graphics card, will not exceed 60mh / s even if it is optimized well. The difference is tens of thousands of times

the purpose of GPU miner is to make money, so we should pursue the power consumption ratio and maximum profit, so we should pay attention to the cost performance. Generally, the medium and high-end positioning graphics cards, such as AMD rx560 and rx570, have high power consumption ratio, which is a good choice for GPU miner. While flagship cards such as gtx1080ti and AMD vega64 have the strongest single card performance, they are not cost-effective in terms of price and power consumption

in addition, the ASIC miner also has some exotic procts, such as the USB miner of burning cat, which is slightly larger than the U disk, and the power consumption is only 2.25w, which is the smallest bitcoin miner at present

the above quoted digcoin.com - "Introction to mining machinery classification" has many professional terms. I hope it can help you, thank you

Just now, as of 23:00 on March 3, bitcoin is now 71976 RMB. At the beginning, when I knew it was very expensive, I also asked this question, how to dig this thing

many mining machines with large amount of calculation will proce a lot of heat in the operation, so they need to consume a lot of electricity for cooling

of course, mining can also be carried out on a small scale with a few mining machines. At this time, you can join the mine to dig with everyone. No matter who digs in the mine, everyone will distribute according to the speed of throwing dice, which can ensure a more stable income

at present, there are many people digging bitcoin, so they have high requirements for the computing power of mining machines. At present, it costs thousands of dollars to dig a bitcoin. Therefore, we should not blindly evaluate the income risk before making a decision

I'm brother Xiaoyu. If you have any questions, please pay attention to me and leave a message below for us to discuss

It depends on the configuration of the computer graphics card and the upload speed of the network. The machine configuration is relatively fast, but it's also probability. It's not so easy. Now many people start to engage in mining, and the unfamiliar people still don't want to play with these things. I think we should first invest in the familiar or online financial management, such as Jujin capital where I put them

With the price of bitcoin rising to a very exaggerated height, bitcoin also has a high degree of topic. Many people have joined the mining instry, hoping to take advantage of this opportunity to get a share, just as about 20% of Internet cafes in South Korea have closed down to dig bitcoin. However, bitcoin is very power consuming. The daily electricity cost alone is an exaggerated figure< this is because bitcoin mining requires computing power, which requires power consumption. In addition, there are usually multiple mining machines operating in a mine, which makes the power consumption of bitcoin mining a very exaggerated figure

in general, bitcoin mining is really power consuming
