It takes 30000 to make bitcoin

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.

First of all, if the home computer is used to calculate bitcoin, even if the configuration is high, it will take several days to dozens of days. It may come out with a string of effective bitcoin (that is, bitcoin), and then it can be traded through the market of circulating bitcoin

special bit code operation requires a lot of graphics resources, so there are so-called mining machines, as shown in the figure below

this is a miner, which is specially used for mining. Such a miner may not be able to dig a bitcoin a day; The price of a mining machine is at least about 20000 RMB, and mining is a very power consuming project. All the graphics cards are running with full load, and the electricity charge will be very high

so don't blindly follow this kind of thing, it's not something that ordinary people can dig up with their home computers

3. If the landlord has spare money, he can go in for a long time and let him go for three or five years. But the premise is that the landlord has a good mentality. In fact, it is quite risky to buy bitcoin directly. Compared with mining, the risk will be much smaller. At present, there are many large mines in remote places like Chongqing and Sichuan, and the mining cost is relatively small, If you are interested, you can go to 58btc and buy your own mining machine to dig bitcoin.

4. Bitcoin Bitcoin is a kind of virtual currency in the form of P2P. Point to point transmission means a decentralized payment system. Bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions
bitcoin is a kind of network virtual currency, which is similar to Tencent's q-coin. You can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items
the biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system has no more than 10.5 million in the first four years, and the total number after that will be permanently limited to 21 million. Another point is that you can use computers to make bitcoin<
detailed introction
bitcoin is a kind of electronic currency proced by open source P2P software. Bitcoin has also been paraphrased as "bitgold". The concept of virtual currency bitcoin was first proposed by Satoshi Nakamoto in 2009. Now bitcoin is also used to refer to bitcoin's open source software designed and released according to the ideas of Satoshi Nakamoto and the P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution, but uses a distributed database throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. For example, bitcoin can only be used by its real owner, and only once, after the payment is completed, the original owner loses the ownership of the bitcoin
features
bitcoin is designed to allow anonymous ownership and use rights. Bitcoin can be stored in personal computers in the form of computer files (wallet) or in third-party hosting services. No matter how it is saved, bitcoin can be sent to anyone on the Internet through its address. The distributed characteristics of P2P and the design of no central management mechanism ensure that no organization can manipulate the value of bitcoin or create inflation

hope to adopt it in time!

bitcoin has become one of the hottest topics at present. however, if we simply regard bitcoin's breakthrough of $30000 as a fraud, then some of them are relatively simple. After all, bitcoin is still of great value as the most valuable virtual currency. The blockchain behind it also represents another development direction. In fact, netizens have had a lot of discussions on this. I have also given other answers to such questions. If you like, you can have a look{ Third, how to look at the future development of bitcoin

in my opinion, after this soaring, bitcoin may usher in a slump in the future. So I hope you can look at such an event rationally. And for those who invest in bitcoin, they also hope that they can treat it rationally. After all, the price of bitcoin has reached the point that ordinary people can't accept. Most importantly, I hope you can understand that we have never acknowledged bitcoin from the beginning to the end

6. Because supply and demand determine the direction of commodity prices. Now the goods are in short supply, because the prices of video memory and various video card accessories are rising, and the cost determines the price, so the price is going up now
in addition, high-end graphics cards and memory moles play chicken eating games. The goods are almost out of stock
now that factories are on holiday ring the Spring Festival, they can't make up for work in a short time, so the price won't drop in a short time. But it's a bit too much to say that the price of graphics card will rise
now that the card grabbers have almost stopped grabbing, the ones that need to be out of stock are out of stock, and the price is quite high, so it is not likely that the price of graphics cards will rise.

7. Who dares to decide whether it's going up or down? I think it's better not to buy it. It's a bit late to buy it after it's all up so high. If you want to buy it, buy less for fun.

8. On January 8, bitcoin was nearly 42000 US dollars. According to the latest data I saw on Hufu exchange, it is about 33000 US dollars at present. You can download a software and receive first-hand messages anytime and anywhere.

9. Because bitcoin is the creator, its position in the whole virtual currency system is also the core, that is, the underlying currency, just like the dollar and other currencies, that is to say, bitcoin is the medium in the digital currency trading system. After all, value comes from cognition. In all ICO projects, bitcoin and Ethereum are accepted. Even Ethereum's crowdfunding only accepts bitcoin.

10. The processing program of mechanical procts is very simple, most of them are programmed by hand, and computer programming is complicated. Generally, there are many mold processing programs without computer programming, so it can only be programmed by computer.

if you want to program, you should first remember the SIEMENS NC programming book, then remember and understand the code, and then try to program by yourself and compare with the existing proct program, It's faster

learn software, learn MasterCAM / UG, Mastercam two-dimensional process is very simple, suitable for machining, UG is generally used for mold, modeling, parting, opening, programming, finite element and so on
