Recently, the price of second-hand mining machines has risen. The dealers of Huaqiang North Mines revealed that the second-hand Shenma M3, which was “two hundred pieces can be bought”, has risen to 450 yuan, and the second-hand ant T9+ has also risen to six or seven hundred. It also said that “mainly miners in emerging mining countries such as Iran are buying. Their industry is in the ascendant, and it is impossible to buy a large number of mining machines and buy expensive high-performance new machines. The road is damaged and fails to be repaired. It’s all a problem, so we will choose this kind of low-cost mining machine.” According to its calculation, the number of second-hand mining machines sold abroad has reached tens of thousands in one month.
