Mining first considers cost and profit. Is it to talk about ideals if there is no profit? Nowadays, my own computer is definitely not good enough. I bought a professional mining machine and put it at home. This electricity fee is more expensive than a professional mine, and the electricity fee is also charged according to the steps. Secondly, the noise of the mining machine is loud, and one is fine. If more than a dozen units are dug up, the indoor temperature will rise sharply. If the temperature does not drop, the machine is prone to crash and trip.
