How much is bitcoin mined by quantum computer

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.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

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

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

3. The desktop can't be g down at all. You can try something else. I'm just digging ITGC, which costs dozens of yuan a day.
the most important thing is that the ITGC client has built-in one click mining! One click mining! One click mining! Important things are to be repeated for 3 times. For Xiao, in fact, mining is not so difficult, as long as there is a computer, a mobile phone can, today teach you a key mining
first of all, we need to download ITGC's wallet client. We can search eppool, Download professional mining tools, and now support PC's win, Linux, MacOS's CPU and graphics card mining, as well as Android mobile phone mining! The second step is to download the official wallet client. After downloading and installing, we start ITGC wallet. Step three, start mining Mining command] enter go and enter to start your mining journey. It's so simple! It's amazing!

4. This depends on what configuration of bitcoin mining machine you buy. Take Avalon mining machine as an example, avalon2
1t package (10 single-mode groups): the price is 13999 yuan; The price of avalon2 single-mode 100g is 1599 yuan; The price of Avalon 2-generation Miner 2 mole 200g is 2500 yuan. At present, Avalon three generation chips have been released, and Avalon 3 mining machine is about to enter the market.

5. The computing power of home PC is too low, and the money earned in a month is not enough for electricity charges, so mining machines are needed
mining is a technical activity, which tests the performance of CPU and GPU. Now on the market, the machine specially optimized for the calculation algorithm of the generation of bitcoin is the miner. At present, it takes about 16000 to buy a state-of-the-art S9 miner on 58btc. There are also special management services, which can save all kinds of troubles. If the owner wants to buy a miner on a certain treasure and do it by himself, he is advised not to dig. You know the reason.

6. This depends on the brand and computing power of the Miner you buy. According to Avalon, the mainstream miner in the market at present:

avalon2 single-mode group
(chip frequency 1500mh / s) ￥ 488 100 g ￥ 4.9 / g 340W ￥ 2.04 / g 0.0037 BTC
￥ 14.11 51 days
avalon3 single-mode group
(chip frequency 500mh / s) ￥ 1, 988 290 g ￥ 6.9/g 342 w ￥ 0.71/g 0.0108 BTC
￥ 40.93 113 days
avalon3
(chip frequency 450mh / s) ￥ 7866 800 g ￥ 9.8/g 822 w ￥ 0.62/g 0.0299 BTC
￥ 112.91 999 days

7. Now that the dividend period of bitcoin mining is over, the output will soon be halved, and now it's a bear market for a long time. Unless you have abundant funds and a very low price source of power supply, you should never enter the mining instry again

8. Mining now? The cost of bitcoin is too high! Now that the situation is over, you might as well know about the Khan currency, which is a real virtual digital cryptocurrency. Now the price is only a few cents, which is very cost-effective. You can know about it

9. In fact, the threat of quantum computers to bitcoin is not mining, but trading attacks. We know that the transaction of bitcoin is completed by decentralized cryptography authentication, and the core of this authentication method is hash algorithm. If there is a quantum computer, it can create collisions (Grover algorithm, polynomial acceleration) to forge transactions for profit. Because the core algorithm of bitcoin has been fixed, if the algorithm is not changed, the key length cannot be increased, and this attack cannot be resisted. However, if there is a practical quantum computer, what can we do is better than this kind of attack...
