Mining is an extremely productive part of the business. Mining of cryptocurrency is the process of confirming transactions before they are placed on blockchain. China is the world’s largest producer of bitcoin mining. There are 6 major mining farms in china presently that produce 60 % of bitcoin supply all around the world!
What is your point of you on this?
Maybe that list is not updated anymore since many mining companies in China already get out of that country and looked for alternative place to mine this is due to the pressure of the government and the unstable stand of China with regards to the legality of Bitcoin. We are close to mine every single Bitcoin, and the next halving will surely affect miners, let’s just hope that its value will rise as well and make mining worth it.
