The best in the IPFs field should be Star Alliance, and the price is very close to the people. At present, there are too many domestic companies selling IPFs mining machines, 300-500 or more. At present, there are only a few companies in the first tier. StarCraft is one of them
Pfsunion Star Alliance is headquartered in Mordor Shanghai. The team is composed of backbone members from Internet giants such as Microsoft, AMD, Ali, Tencent, sap, Huawei, Shanda and Yingyeda. It has a mature and complete instrial supply chain, and has many branches and partners at home and abroadsince its establishment, Star Alliance has focused on the research and development of blockchain technology with the support of technology, focusing on building a global IPFs ecosystem around IPFs filecoin, providing mining machinery, mining, hosting, data, application, knowledge, and marketing services

2. With the coming of the main network, the layout has begun. First of all, it is necessary to choose a technology-based mining machinery hosting company to cooperate, because once the main network is online, the strength of each technical team will decide whether it can grab more orders faster and dig more money than others. At present, the hard disk is almost Seagate, regardless of cloud computing power or physical hosting. In general, the technology of IPFs is revolutionary
in the bitcoin network. Every transaction information is recorded through consensus. The people who take part in these records are called miners. Miners have two responsibilities: one is proction block, the other is accounting. If no one takes part in the work, the bitcoin network will be paralyzed, and those who take part in the work will be rewarded with bitcoin. Bitcoin is mining with pow. To put it simply, more is more. But now with the increase of computing power. Mining is becoming more and more difficult. The return on investment will be lower and lower. I hope it will help you.
