Why don’t the bosses who sell mining machines mine Bitcoin themselves?

I see a lot of people selling Bitcoin mining machines. Why don’t they go mining? Can they make more money selling machines than mining Bitcoin?

In fact, this problem can be transformed into:

1) Boss who sells coal mining machinery, why don’t you dig coal yourself?

2) Why don’t engineering companies that build highways build the highways themselves and collect tolls?

3) Why don’t the companies that build high-speed trains carry passengers themselves?

In a complete industrial chain, equipment manufacturers, product producers, channel operators, retail cash providers, etc. form the industrial chain. Everyone has different divisions of labor, and in these different divisions of labor, they jointly obtain profits in the industrial chain according to their contributions. This is a complete industrial chain.

In the current complex production system, there is almost no one company that can handle everything from the source to the terminal. Alibaba is very powerful, but it still cannot intervene in the production and logistics system. It is just a platform.

By extension, this kind of industrial chain distribution is also seen between countries and continents. The Middle East, Africa, and South America provide raw materials for the world's industrial chain, East Asia and South Asia provide processing and manufacturing services to the world, consumption is in Europe and North America, and Europe and the United States provide technological development and financial services for the chain.

If we narrow the matter down, no matter how capable a person is, he can't twist a few nails even if he is made of iron. So it is a matter of seeking truth from facts to think carefully, find your own position, and find your own suitable position in the industrial chain.

Specifically in the Bitcoin chain, the bosses who sell mining machines may have good basic tool advantages, but where does the raw material for mining - cheap electricity - come from? You have to go to the mountainous areas of Yunnan, Guizhou and Sichuan where there is abundant hydropower and surplus electricity. You have to get to know the locals, make connections, build a mining farm, and find people to operate it without problems. Once these conditions are met, it is estimated that 80% of the mining machine owners will be eliminated. There are other additional conditions, and many people really can't do this job.

On the road to gold mining, boat tickets are the most profitable. Those who dig coins are all gold diggers, and mining machine manufacturers are the ones who sell water and shovels on the road to gold mining. As the saying goes, there is a sequence in learning, and there is specialization in skills. Just do your own specialty well, and you can't make money from anything.

The purpose of the existence of enterprises is to make money. Since selling mining machines can make money, why bother to get involved in the mining industry? Bitmain's Wu Jihan is worth tens of billions just by selling mining machines, and he mines on a large scale in many countries. It is also very restricted. Since selling equipment can make money, why bother to mine?

For example, in the e-commerce industry, I don’t know whether it makes money or not, but I know that the agents who operate it must have made a lot of money. I don’t know whether the merchants make money through the popular mini programs, but the companies that help develop the mini programs must have made money.
