The best bitcoin speed of graphics card in 2009

1.

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. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing

2.

Bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners

advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to

the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)

people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)

I hope I can help you

3. You need to share invitations, download friends, browse news, read novels, watch videos, etc., to earn gold coins and then change them from gold into WeChat coins or Alipay, or directly recharge phone bills, Q coins, etc., which requires WeChat WeChat real name authentication. So it's not easy to make money by mobile phone. Some software has high threshold and earn a phone fee. Or find a job to earn more than this, but also exercise themselves, often play mobile phone is not good for the body, their discretion to consider it

4. This is legal in some countries, and the domestic attitude is not very clear. Anyway, it is not illegal

5. A distributed ledger technology of blockchain! The jester of ether doesn't know what it is, so we should be cautious

6. Generally speaking, AMD's graphics card is more suitable for the most mining graphics card e to the factors of architecture, price and so on
hd7990 is the current king. It is said that the electricity charge for mining each bitcoin is 130-140 yuan. In other words, a monster card like hd7990 needs to work for about 20 days to get a bitcoin. A bitcoin may consume 300 watts of power, not counting the loss of computers
in addition to the graphics card, other hardware of the mining platform will also consume electricity. CPU / motherboard, memory, hard disk, including the power supply for the whole machine, will still need electricity because there is no 100% conversion rate. Compared with the display that can be turned off in pure standby, they have to intervene
the faster the graphics card mining speed is, the less unnecessary power consumption will be consumed for each bitcoin acquisition. In this case, the graphics card with fast computing speed often has more advantages. If a multi card platform is established, the net profit per unit time will be higher
the lower the performance of the card, the more power it consumes on average
in a word! Investment must be cautious.

7. Don't dig this video card. You can't get one even if you dig it for a few months. The electricity and Internet charges are enough for you. It's not worth your life to pay for the dead

8. It must be a card. Now most of them are digging with 7850

9. Normality, you do not know, you need to know the way, I'm I3, 3 to 4 m seconds, you will not be able to play I want you to be an associate

10. At present, the most cost-effective is still the power consumption and price of 5850 / 58707950. It is not recommended to start from now on, because the whole mining is based on the network credit, and the tide will collapse as more and more people. For example, if the 5850 / 5870 has a rate of 0.3 g, the 7950 is 0.5 g. by comparison, which is better or worse, you probably understand
