1. CPU can be used to mine, but the efficiency of CPU mining is not as high as graphics card. In order to make money, absentees have to calculate the input-output ratio. The input-output ratio of mining with graphics card is higher, so we graally start mining with graphics card. Now you should understand why mining with graphics card does not use CPU.
2. Zcash, which is called zero coin in Chinese, is known as the most anonymous digital currency in the world. bitcoin was once in the limelight, and its price was second kill. But then all the way down, the concept stock is no longer a myth, it still needs time to accumulate. Now, the price has fallen to about 300 yuan
there are platforms supporting zero currency trading in China, such as cloud currency, bitcoin, and foreign P network
however, this kind of digital currency still needs careful investment, and the risk is too high, which is different from the fixed income token launched by European crowdfunding platform.

Btcv is a mineral coin g by POW mechanism, not an air coin issued out of thin air
The full name of btcv is bitcoin vault, and its Chinese name is bitcoin vault. It is a digital currency dedicated to modifying the defects of the original bitcoin protocol. Btcv coins were issued in October 2019, with a total issue of 21 million btcvbtcv provides a high security blockchain ecosystem based on triple key system. It retains all the conveniences of bitcoin, and increases the important functions of transaction transparency and freedom. Btcv currency is a new type of digital asset that integrates the experience and lessons of the past decade in the field of digital currency
extended data
btcv is designed to be compatible with the standard bitcoin protocol as much as possible. The basic goal is to minimize the necessary code changes to all existing bitcoin nodes, wallets, mines and mining machines
however, if the existing blockchain is changed, it needs to implement hard bifurcation. In order to avoid changing the format of the block header and making the cryptocurrency incompatible with the bitcoin miner, the Merkle root hash value of the reminder part is stored in the input value of the standard coinbase transaction
if we need to implement hard forking, our goal is to make the transition as easy as possible for existing cryptocurrency users. All existing script classes do not change their behavior, so all cryptocurrencies existing before the implementation of hard fork can be spent in the usual way. But we strongly recommend switching to a new, more secure script
4. Recently, workers have been crying. The price of computer graphics cards has gone up too much. 6000 yuan without a display can't get the 2060, let alone the 3060. How can it be more cost-effective
as you know, with the rapid rise of the currency circle, the graphics card has changed into a "financial card", giving you eight words: "be careful to reload the machine" and bear the loss
1. What are the main reasons for this round of price rise of graphics cards
some people say that with NVIDIA's proction capacity and the price of virtual currency, you can't expect to have the original price card. It's not that the factory can't raise the price. People who are "mining" are waiting at the gate of the factory to increase the price directly. There's no reason not to sell it
in my opinion, the price increase of graphics card is mainly caused by insufficient chip capacity and the demand of coin circle mining<
1. Insufficient chip capacity
affected by the epidemic in 2020, the global chip supply chain is tight, and the capacity of graphics card chips is also insufficient, and the market demand exceeds supply, which leads to the shortage of graphics cards, the scarcity of goods is more expensive, and eventually the scarcity of graphics cards will soar all the way
2. The demand for coin circle mining is growing
just as Ethereum virtual currency rises from more than 800 yuan in early 2020 to nearly 8000 yuan by January 15, 2021, the main tool for mining is graphics card, which depends on multi graphics card calculation to obtain virtual currency. A mining machine needs at least 6 graphics cards, and at most 12 graphics cards or more
with the rising price of Ethereum virtual currency, Ethereum has huge profits. In order to get a large number of graphics cards, these "miners" are willing to increase the price to buy graphics cards, which leads to the shortage of graphics cards in the market< When will the graphics card shortage last
on February 24, the marketing department of jiahejinwei issued a "warning" about the shortage of wafer supply and the shortage of DRAM and nandflash chips for manufacturing memory moles and solid-state drives, which led to the rise of contract prices. Therefore, we can speculate that the price of memory will continue to rise in the first half of 2021, or there will be no price increase and no stock available
however, this is just a prediction. As for when the price increase of graphics card will end and how long it will last, no one is sure. If you want to completely solve the shortage problem of graphics cards in the market, there are only two situations at present:
the first situation is that NVIDIA and AMD official or chip foundry can increase the proction capacity of graphics chips, and launch professional mining cards to alleviate the shortage impact of mining on the market
or wait until the new card is released, the new card is not 3060 (2070), but 3050 or 1750. Anyway, it's a new card to replace the original 1650s and 1660, which are really entry-level sweet grade graphics cards. In particular, whether ADM can launch the new card as soon as possible to compete with NVIDIA
another situation is the collapse of virtual currency in 2018, and the prices of bitcoin, Ethereum and other digital currencies are falling all the way
if you really want cryptocurrency to have a "mine disaster", then they must continue to plummet for a period of time, so as to cause greater reaction. The retail miners leave the market, and a large number of mine cards flow into the second-hand market. Fewer miners buy graphics cards, and more players will be left. Miners selling cards will graally lower the second-hand price, and graally both the new and second-hand prices will come down
I don't know from what point this outbreak will start, maybe now, maybe in the future
generally speaking, the price rection of graphics cards will be relatively slow this year. Even if it starts to fall sharply from now, the price of 618 may fall to the price of 30 series released last year when 618 is promoted in the middle of this year, that is, 3080 is about 7000, 3070 is about 5000. Of course, this is only possible, and the worst case is that this year is the same price< Third, the price of graphics card is too high. Is it worth buying
the increase in the price of graphics cards will undoubtedly bring more costs to the installation. For ordinary consumers, it is definitely not worth it, which is beyond doubt. Generally, we have the following choices for the current shortage and rising price of graphics cards:
1. Wait, wait, wait together! If you have a computer at home that you can barely play with, just wait for the graphics card market to return to normal
2. If you really need to install the machine, you can first configure the host computer, graphics card and so on. Start with the graphics card of the old computer or the second-hand platform, and use a graphics card that can meet your needs first, and then add or upgrade it later
3. If you are a local tyrant, or some professional work requires high-performance graphics card, and those game players have to play in this period of time, you can only bear to buy a card
generally speaking, you can't see the possibility of a significant decline in the short term. If you want to equip your own desktop, the cost performance is very low. The configuration that you can land on more than 7000 in peacetime will cost 10000 now. I suggest that you can buy brand computers from first-line manufacturers. Although there is a premium, compared with the current "wartime state", you can assemble 10000 or 8000 yuan brand computers with high cost performance
in short, e to its unique hardware architecture, GPU is naturally suitable for mining, which leads to the shortage of graphics cards in the hot market of digital currency. If the graphics card wants to return to the normal price, the restrictions of upstream manufacturers can play a certain role, but it mainly depends on the historical process. I hope the global economy can return to the right track and give the digital currency speculators less reason to speculate.

8. The performance of rtx2060 and gtx1080 can be said to be on a par. This is not an upgrade
if you want to make a big improvement in your configuration, i7 4790 is not very good. The improvement is not big. You'd better change the platform directly. The memory bandwidth is also greatly improved in some games
it is recommended to buy two i7 9700f + b360 motherboard + 8g memory.

1080 resolution within the basic seconds of all the Games
2K resolution can also open relatively high image quality, smooth operation
only 4K resolution need to change stronger graphics card,
if the resolution is less than 4K, do not need to change, to improve the number of frames mainly depends on the CPU, graphics card performance is not enough, slightly lower the image quality in the game
