the sharp drop in bitcoin price will push up the price of mining machinery in recent years, e to the sharp rise of bitcoin price, many people began to increase the purchase of mining machinery, which directly pushed up the price of mining machinery, and even once there was a situation that mining machinery had a price but no market. The mining machines are out of stock, and many mining organizations have turned to the graphics cards for ordinary PCs. as a result, the graphics card market has been quickly snapped up. Many computer enthusiasts often complain that the price of graphics card is too high. This time, the fluctuation of bitcoin price will undoubtedly affect the price of mining machinery, especially the Chinese market, because the government wants to eliminate mining organizations in China, which is undoubtedly a blow to the mining machinery market
this bitcoin crash is the best proof. However, subject to the boom of bitcoin investment, it is expected that the price of mining machinery will not come down in the short term. After all, compared with investing in bitcoin, it is obviously less risky to buy mining machines for excavation. Because the mining machine can be sold as a second-hand graphics card in the end, if it is directly invested, it may lose all its money, so the global mining machine price may still be very high, but the domestic mining machine price may go down
