Price increase of mining machinery in 2019
because the essence of filecoin mining is storage, from the perspective of data security, most mining machinery manufacturers currently use 8t enterprise class SATA mechanical hard disk, with a price of about 1300-1500 yuan. A few mining machinery manufacturers choose 10t or 12t, and they basically choose several mainstream brands, such as Seagate, western data or Toshiba, A 12 bit blade server with 8t hard disk can have 96T storage space
SSD is generally not considered, because the cost performance is low, and if the data is lost, it is difficult to recover. If the data is lost ring the mining of filecoin, there is a penalty
generally, the CPU of mining machinery will choose inter or AMD platforms. Some mining machinery manufacturers only list inter E5 level, but do not specify that it is E5 with several cores. We must pay attention to the official requirement of minimum 8 cores
only a few single machine mining will use Inter's E5, E7 or AMD 3970x. The more mainstream mining association will choose to use the affordable amd platform with high cost performance for cluster mining. Few people choose the inter platform. Moreover, single machine mining requires high memory and low cost performance
AMD epyc7302 and 7282 series CPUs are the mainstream choice of cluster mining. They have been out of stock recently, and it may take half a month or even a month to adjust the goods. Moreover, the price of related accessories suitable for building filecoin mining machine is rising recently. For example, in 2019, the price of h11ssl-i ultra micro server main board is about 3000 yuan, At this stage, 5500 yuan can only take the futures after a week, so it is difficult for people who have no relevant channels to assemble their own accessories. Whether it's accessories or finished mining machines, it's almost one price a day
considering that each person's specific cost of taking goods is different from the cost of assembly and configuration, we can calculate the cost of a mainstream 96tb miner. If we have accessory related channels and have the strength to assemble, the cost is about 50000 yuan. If we buy finished procts directly, it is about 80000 yuan
if you want to buy the most affordable IPFs filecoin miner, you can pay attention to our company Zhonghao: old Chen Shuo coin
25000 mining troops in Sichuan: a flood cost hundreds of millions, most afraid of power failure and loneliness
these computing power are scattered along the Da River, a tributary of the Minjiang River. They inlge in the night of Dalate Banner in Ordos, and sleep soundly in a small city in Yili Kazakh Autonomous Prefecture of Xinjiang
today, bitcoin's total network computing power has reached about 30 billion hash collisions per second, equivalent to about 600 tianhe-2 supercomputers, and it is still growing at a high speed. " Wu Jihan, the founder of bitcontinent, wrote in the beauty of computing power
he preached a set of infinitely beautiful "computational aesthetics", but behind the aesthetics is the cruel computational world and interests. Mining is moving towards instrialization step by step and becoming a game of capital
at this time, decentralized mining machines and pools began to appear. They called themselves revolutionaries and wanted to change the extremely monopolized bitcoin world
"cloud computing power mining" is one of them
their way of playing is to establish a number of distributed mines and provide computing power leasing services with tens of thousands of real mining machines
"the current computing power is too concentrated, and some decentralized play methods are difficult to change the current pattern and ecology." Li Ke said
but the essence of blockchain is decentralization. The miners still have the belief that eventually the mining instry will be broken by the decentralized mining pool
this may be the only belief that keeps them going
how long will it take
"5-10 years, slowly nibbling at the giant's territory." Li Ke said
but will giants wait for the revolution? Will they fight back
the battle of computing power and the spark of revolution have just been ignited

there is another way to solve the problem of not recharging the PayPal account to the US dollar. It is through finding a person to exchange PayPal dollars (using RMB in a certain proportion of exchange), the other party pays the US dollar through your PayPal account to your PayPal account, and you send the remittance through Alipay or domestic bank to the right side, so as to solve the problem of recharging the PayPal account to the US dollar. At present, only local banks in the United States can recharge the PayPal account in US dollars (for example, the Bank of America account you applied for in Shanghai can't be recharged in PayPal), and the PayPal account can't be recharged in RMB.
friendly reminder: you need to find a reliable payer in this way. At present, PayPal certification supports a variety of international credit cards. Certification is very simple. It is recommended that you apply for an international credit card of China Merchants Bank, and you can pay directly through the credit card when shopping.
the work of PayPal consultants is not only to guide customers to register, but also to maintain their accounts in the later stage, for example, customers can't receive the money they call you, If you can't withdraw cash from your bank account or some people have problems with limited accounts, you can ask PayPal customers to help you solve them. Even PayPal consultants will teach you some tips on how to use PayPal, how to use PayPal to save handling charges, and risk control knowledge. If you use it for the first time, do you need a consultant?
1. Virtual currency may continue to develop for a long time. Due to the high security of virtual currency, it can't be issued at will, and Chinese and foreign people can't identify the user's identity information in the transaction process, a large number of people have a crazy pursuit of virtual currency
2. Virtual currency may be involved more widely in the future. As long as someone recognizes and uses virtual currency, the existence of virtual currency has value
virtual currency has been developing so far, prosperity and bubbles, wealth and dreams, questioning and supervision are all on the way. Investment is risky, so we should be cautious. At present, such playing methods as bitcoin have not been approved by the regulatory authorities. It is suggested that ordinary investors should participate in the game within their ability.
the price rise of CPU is also e to the upsurge of installation. With the coming of summer vacation, the installed capacity of users increases. There is also a part of the mining machine also needs CPU. In addition, SSD is also rising in price, because manufacturers have not yet come out from DDR3 to DDR4, the proction capacity is not high, and the demand for graphics cards and installed capacity have increased greatly, resulting in DRAM supply can not come over.
