The trick behind the virtual currency second-hand mining machine: "mining machine mode" pyramid scheme

According to the Beijing Business Daily, the “second-hand” bitcoin mining machine was sold off after the Spontaneous Reform Commission included “virtual currency” mining activities in the phase-out industry. At the same time, some illegal pyramid schemes using the concept of mining machines have emerged in an endless stream. In the opinion of analysts, some miners use similar pyramid schemes to sell mining machines, and the mining machines that investors take over are difficult to generate actual mining revenues, and eventually evolve into relay games, and there is a risk of collapse of the overall model.
