How much can mining earn in ancient times

1.

as a middle-aged miner for 13 years, let's talk about the feeling of mining before.

I bought four mining machines in the past. bitcoin uses CPU and I'm not familiar with it, so I use the form of buying graphics card to dig Wright's coin.

the first one is a simple double card mining machine, not a mining machine strictly speaking, but a double 7950 machine, At that time, I thought about digging for a while. If I didn't make money, I could still play games by myself. As a result, I found that the efficiency was really not high. Later, I used to dig some dog money and play with it.

the second one was the popular 6-card miner in those years. At that time, there was a powerful motherboard, which could run for 6 yuan by connecting with the PCI adapter and changing the BIOS. At that time, I could dig a lot of Wright's money every day with this machine, It's a pity that there are too many people digging, so it took more than 80 days to dig the coins. The third and the fourth are professional mining machines. At that time, the new chips were used to mass proce mining machines. Although they were expensive, the power consumption decreased a lot. It took about a year to dig, In the end, he retired, g up other counterfeit coins for a while, and then sold them.

generally speaking, many websites have no credibility at all in the past few days. They actually know what the concept of excessive increase in computing power is after digging up the money.

when ZF suppressed it, the assets immediately shrank by nearly 70%, but they still didn't sell because of their faith, On the contrary, after selling the miner, I bought some coins and put them in my hand. When I bought 100, I g them and only bought 15. Hey, the miner was sealed and put under the bed. After waiting for three years, I found that it rose again. This year, when bitcoin rose to 2W, I sold some Leyte coins and paid the down payment. Almost 300 of them were sold. Now it seems that the highest is 380, Ha ha

now I still have some money in my hand, and I plan to hold it for a long time, but I won't dig any more. However, I still have a lot of orders with our first-class suppliers. In the past two months, I sold nearly 150 cards, and the more I sold, the more I sold. Some cards are about to double, which is even crazier than that in 2013, The existence of e-money has its own value in the end, but it does not deny that there are so many speculators who come in to fight. There are indeed those who pursue the price. After the boom, there will be a wave of leeks cutting. In the final analysis, bitcoin is just an investment. Everyone feels different about the risk. The strength of big funds is still strong, and it is inevitable for retail investors to be cut, But it's better than A-share at least.

mining is not a good thing. The big miners are in the remote areas with low electricity charges, many mining machines and low cost. Most people dig at home, and that's just a little fuss.

finally, it's not a good thing to grow too fast. Those who are confident can come in and show their operation. If they don't have much ability, don't come in, Only by routine

2. Starting to look for a job in 2018 has been very difficult. It took a long time to find a start-up company with less than 10 people. At that time, I learned that it was a company doing digital virtual currency exchange and DAPP. At that time, I didn't know anything in the interview. I thought there was no hope, but I called the next day to come to work directly. I was so excited that I finally found a job
I have been working in this company for one and a half years since May 2018, and I have been outputting works all the time. I seldom output some theoretical articles, so now I want to sort out my understanding of blockchain and how to do design after more than a year's work. There are also some preparations for those who are going to interview with blockchain companies.

3. In the past, it was a good thing to have a few hundred birds in one day. It's a bit exaggerated to have a big bird in two days. Later, there were more people washing and mining, and they couldn't grab the mine. Now the forging projects are full, and the market demand of the mine is low. It's definitely not enough to make money only by mining. It's better to do the daily task and brush the to make money. After all, mining still needs some luck, I can't make 100g in a few hours without luck. It's real money every day

4. 1. In October of last year, we g thousands of gold in one hour and tens of thousands in eight hours
now the price of the mine has depreciated by 90%, so it's good to dig up thousands of gold. It's not worth it.
2. I can earn so much even if I go to toss ah for 8 hours, but the market profit is too low to bother
3. At the present stage, Youming iron ore is easy to sell, with a group of 40. But you need a full class number. The lower class can't fly and dig fast.

5. What are the current challenges of blockchain
at this stage, the application projects in the blockchain field are mainly divided into two aspects: one is the new business model that is more compatible with blockchain technology, such as cross-border payment, supply chain finance, proct traceability and other scenarios; The second is the application of the reform based on the existing centralized business, that is, the use of token economic incentive mechanism
with the development of technology, the number of application projects in this field is expanding rapidly, and many people believe that 2018 will be a year when blockchain will really combine with the real economy and break out. However, blockchain technology is still in the early stage of development, facing challenges including regulatory environment, lack of talents, technology awareness and so on

from the technical level, the application of blockchain technology to the actual instry scene needs to solve the problems of transaction speed, data consensus, node maintenance and so on. At present, bitcoin network can only process seven transactions per second, and the leading super ledger technology can only reach the level of 200-300 transactions; This is a long way from a centralized system with tens of thousands of transactions per second. In addition, the lack of relevant incentive mechanism in the field makes it difficult for participating nodes to operate orderly. From the regulatory perspective, although most countries actively embrace blockchain technology, there are no relatively perfect regulatory regulations and instry standards at this stage. Inappropriate regulatory measures may hinder the innovation and development of such emerging technologies
it is affected by many factors, such as the underlying technology needs to be further matured, the lack of intelligent contract public chain platform, the lack of ecological compatibility of all kinds of token, and the unclear government supervision; At present, the implementation of blockchain application projects is relatively slow, and the project quality is uneven. To this end, analysts said that compared with the general blockchain, the focus blockchain for specific scenarios and applications may be a breakthrough in the short term.

6. No, if you mine 24 hours a day and 20 hours a day, you will definitely be judged as robot mining. But the mining time distribution of ordinary players is different. Let's have a meal and do something else. The activity time is different from robot mining. No problem
there are miners in the United States~

7. It's about three times in an hour, and the purity is not necessarily ~
it's recommended to connect with the strong wind ring, and then add the accurate Bracelet (sharper bracelet) to the strong wind ring

8. 1. Professional graphics card, in fact, its hardware cost only accounts for a small part of its price, more value-added in the driver development and ISV professional software certification, so as long as you use Maya, 3ds max, SolidWorks and other software, the performance and value of professional graphics card can be realized, When you open a complex scene for editing and modification, you will be able to provide a preview at real-time speed without lengthy waiting... This is impossible for ordinary game graphics cards (even the top-level GTX 580590, these game graphics cards are also in this aspect)
2. The game performance of professional graphics card is almost the same as that of ordinary graphics card with the same core. The new generation NVIDIA Quadro 6000 professional graphics card adopts the same display core and proction process as GTX 470. The video memory adopts 6 GB, gddr5; The game performance of NVIDIA Quadro 6000 professional graphics card and GTX 470 is almost the same, so professional graphics card can also play games. But the reverse is not good, game graphics rendering is not good
3. The price of NVIDIA Quadro 6000 professional graphics card is as high as $3000, while the price of GTX 470 with the same core is less than 1 / 10, about $250

9. Graphics card
includes game graphics card and professional graphics card
game graphics card is the NV card and AMD card that we usually use
