First and foremost, I don't really think I agree with you on the argument that mining is centralized. Do you really understand how the entire system of mining works ? please you need to eleborate the basic reasons why you thing is centralized in the first place. Because I think a lot of people on this forum wanna know what exactly you have seen to finally conclude on this.
Its hard for me to understand what you cannot understand in the word centralization. All mining is in the hands of a small group of very wealthy farmers. Farmers are controlled by the government of the country in which their mining farms are located. The governments of different countries are controlled by the international government. This is centralization.
So that mining is not called centralized, it must be decentralized. Decentralized mining is when anyone can participate in mining using their own computer or smartphone. This cannot be controlled. The government here is powerless.
If you do not agree with this, I can do nothing about it. A rich man who does nothing useful but sits on a big mountain of gold can also call himself a hard worker. But the truth is that the real workers are those who mined this gold from the mine. And one lazy person cannot get a whole bunch of gold. Therefore, when one farmer owns a mining farm of 1000 THash, and millions of people around the world cannot even get 1 satoshi, then this is not fair. And Satoshi Nakamoto created Bitcoin to overcome this problem. But this problem overcame both Bitcoin and Satoshi.
Therefore, it doesnt matter to me whether you agree with me or not that Bitcoin is centralized. It is centralized. It is a fact. But you can not admit it, you have the right to it.
