Hello, I am a mining equipment supplier in China, I will answer your question. Because under normal circumstances, manufacturers such as Whatsminer or Antminer will invite us to place an order to buy a futures mining machine a few months before the production of a mining machine. When we complete the procurement, they will arrange the production tasks according to our procurement situation, so that their risk will be much smaller. So all they produced were bought by us, and there would be no inventory on his official website.
