According to media reports, Ukraine recently destroyed an illegal underground mine in Vinnytsia.
After investigation,The mine has 3800 PS4 hosts, over 500 graphics cards and 50 CPU processors,In addition, notebook, mobile phone, flash disk and notebook were also seized.
Although the single precision of the early generation of PS4 is only 1.84t, the existing bandwidth is 176gb / s, the PS4 Pro is only 4.2t, and the bandwidth is 217.6gb/s, so the mining efficiency is not very high (in fact, the bandwidth of rx580 is only 256gb / s), but the problem is that the mine is illegally connected to the power grid, that is, mining by stealing electricity. It has almost no cost, and it is a business with huge profits.
In other words, if the calculation is low, you can not touch bitcoin, ether bank's high and hot currency, and a large number of small coins and miscellaneous coins can be set foot in.
It is precisely because of the steep increase in electricity consumption that the law enforcement departments pay attention to it.
