Mining at home in 2020

1.

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

2. Now the mining machine is generally not big, and the computer host should be smaller. Mining needs to be added to a mine pool, which cannot be g by itself. Now mining has been close to or even more than the currency price, if the electricity charge is free, you can go to mining. Mining power is very large, and you need to install refrigeration equipment. The noise is also very loud. You should also pay attention to this. The noise of the miner of ants is relatively small. The ant miner is OK. If you buy a miner, don't buy a second-hand miner. It's not worth it. The miner's update speed is amazing. If you don't understand, please send me a private letter.

3. BTD is the most popular

4. At present, the most power-saving mining machine on the market is the ant mining machine S7, with 4.73t of computing power and about 1200 watts of power consumption. The power consumption of other mining machines with the same computing power is far greater than that.

5.

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

6. You have enough money to support your daily life. That's the premise
mining needs time, money or space, not just shouting
if not, it is not recommended to stay at home. It requires more energy. If you do, you may not get it. More likely than not
Mining sounds good. In fact, it's just the pain on the surface and behind. Who can say
don't look at making money, it's only a few people who make it, but more people make soy sauce
if you go out to find a job to do mining, don't think about it. It's not suitable.

7. 1. Control
generally speaking, bitcoin and cryptocurrency tokens provide you with more control. You effectively cut the middleman between you and your money. No bank can decide how long a transaction will take and how much it will cost. You can also control where funds are stored and how they are accessed. Of course, control brings corresponding responsibilities
2. Affordability
since the middleman is not in the picture, you can save some transfer fees. Moving bitcoin from one wallet to another costs a negligible amount of money. It is cheaper for businesses to accept bitcoin payment than credit card payment
3. Speed
in addition to saving international transfer fees, you can also enjoy higher transaction speed. What does it take your bank a few days to do? Bitcoin can do it in a few minutes
4. Convenient
with bitcoin, online payment is easier and faster. If you want to donate or pay for something that will not be delivered, you do not need to disclose any personal details. Just send bitcoin to their wallet address
5. Security
it is safer for businesses to accept bitcoin than fiat money. When businesses accept credit card payments, they risk fraud and reverse payments. Bitcoin payment is irreversible, so there is no risk of reversal
6. Privacy
one of the main advantages of using bitcoin is that it provides privacy and relative anonymity. You don't need to provide any personal details to access the bitcoin wallet. All you need is a device to store it - even a piece of paper. Bitcoin transactions are only linked to your wallet address
7. Reliability
bitcoin network is essentially a point-to-point payment system. This allows you and you to remit money to anyone who participates in the party. You don't have to rely on the bank to do the work to make the transaction effective. In Ethernet, the risk of payment loss is small, which eventually makes it a more reliable way of payment
8. Investing in
bitcoin wasn't worth a lot of money ten years ago. Let's see where it has been since 2009. From a few dollars in December 2017 to nearly $20000. At the time of writing, it is now stable at around $6000. As more and more people adopt bitcoin, bitcoin will not be everywhere. Investing in it may be risky, but it's absolutely profitable.

8. Mineral processing is a hard work environment (remote mining area), but compared with mining, it is still much better work. The coal preparation plant will be a little worse, with a large amount of coal ash. Metal mines are very clean, and now large mines are automated management. Associated with mineral processing, the one that can be tested for postgraate entrance examination is mining. In the future, the development direction is mine manager, who knows both mineral processing and mining, and is a comprehensive compound talent. It's what the mine needs.

9. Mining machines need to be looked after from time to time. Mining at home not only takes time, but also needs to know how to operate. Now most mine owners will choose the computing power of interstellar ants to operate with full transparency and support trusteeship. They have Alibaba cloud technical support for operation and maintenance every day. Just wait and collect money. Why not.
