Where to buy Bitcoin mining machine? How much does a Bitcoin mining machine cost? As the difficulty of mining Bitcoin increases, personal computers can basically bid farewell to the mining industry, because you have to wait hundreds of years to mine, and I am afraid that the family has changed for several generations. Besides, The huge expenditure is also difficult to afford. Therefore, Bitcoin mining machines are now used for mining. In fact, Bitcoin mining machines act as computers, but they have greater computing power and higher mining efficiency than computers. So here comes the most important question, where can I buy a Bitcoin mining machine?

It is generally best to go to the official website of a manufacturer that specializes in producing Bitcoin mining machines. On the one hand, you can save time and money because you don’t have to go back and forth, and the relevant introductions on the official website are more detailed; on the other hand, the official website will not sell fake products, and the after-sales service is guaranteed. You can also go to major e-commerce platforms, which is more convenient. You can also check the reviews of people who have used them, which gives you a wider choice and is more targeted. Another way is to go to a shopping mall or specialty store that sells mining machines. The price should be a bit more expensive, but you can see the real thing for the first time, and you can also compare different mining machines in real time, which will help you choose the most cost-effective mining machine.

You can also directly contact the manufacturer of the mining machine online. It is best to be a professional manufacturer of mining machines, or someone who has been engaged in related industries for many years and has guaranteed technology. After all, Bitcoin is so popular and the demand for Bitcoin mining machines is also relatively large. It is difficult to guarantee that some manufacturers will fish in troubled waters and make unintended money. When preparing to place an order, it is best not to pay first, especially if the manufacturer advocates payment first. It is very likely that there is money fraud, so be careful. You should also read relevant materials and product information carefully to choose the Bitcoin mining machine that best suits you.

In 2009, when Bitcoin just came out, you could buy 1,300 for 1 dollar. In 2010, an American named Laszlo purchased 2 pizzas with 10,000 Bitcoins, which was the first commercial transaction in the history of Bitcoin. Behind the crazy surge in Bitcoin, a group of miners have emerged who make a living by mining. They buy machines and graphics cards and want to participate in the feast of the skyrocketing Bitcoin value. However, with the implementation of strict regulatory policies on initial coin offerings (ICOs) and Bitcoin by regulatory authorities, Bitcoin China, Jubi.com, .com, Okcoin Coin Bank, etc. successively stopped all virtual currency exchanges at the end of September and October 2017. Currency trading business. While various continents are continuing to close trading services, some domestic "mining machines" that mine Bitcoin are losing their usefulness.

Currently, major QQ groups, WeChat groups, and Xianyu websites are selling “mining machines” and graphics cards used to mine Bitcoin that were once in short supply at low prices. On the second-hand "mining machine" trading website Caiyunbit and the second-hand trading platform Xianyu, it was found that in recent times, there has been an increase in information about the purchase and sale of Bitcoin "mining machines" and graphics cards, and they are all sold at significant price cuts. One machine once cost tens of thousands of yuan. The Ant S7 mining machine can now be purchased for as low as 1,400 yuan. On the Caiyun Bit website and the Xianyu website, a large number of information about the purchase and sale of "mining machines" and "graphics cards" appeared, and the prices were at a significant discount compared to before. On Xianyu, someone even sold a mine with an original price of about 12,000 yuan for 800 yuan. Of course, there are fakes among Antmint S7 and S9, so you should keep your eyes peeled before buying them.

During the heyday of Bitcoin mining, the price of mining machines ranged from 10,000 yuan to 300,000 yuan depending on the configuration. Mining machines with higher configurations could mine 3 Bitcoins a day. Graphics cards have gone from being in short supply to being sold at low prices, and no one cares about them. This is because Bitcoin’s computing power has increased, mining difficulty has increased, and profits have also declined. The mining difficulty increased on November 2, 2018. By December 19, the continuous decline reached 32.08%. After that, there was a continuous increase. Compared with the same period in 2014, the situation was similar.

If you already understand the risks and costs of this industry, then go ahead if you want to mine. This is a far-sighted investment. If you are not so courageous, but still want to take the plunge, you can consider some online mining platforms that provide a full range of hosting services. Mining is not a game where the outcome is determined by one move. Coins can be stored and dormant. , that is to say, what each miner strives for is not only strong financial resources, but more importantly, confidence in Bitcoin.
