The difficulty of bitcoin mining will be adjusted according to its network computing power/hash rate. The higher the computing power, the higher the difficulty is to maintain the same block excavation ratio. However, from October this year, the difficulty of mining is in accordance with the bit. There has been a rare decline in the decline in the power of the currency network. From August to November, the computing power dropped by 24%, while the value of Bitcoin also showed a significant decline in November, and the current currency value remained at around $4,000.
A decrease in computing power means that some of the original mines were closed or transferred to other digital currencies. If it is intentionally closed, it is obviously because the current currency value is not economically economical for miners.
The mine's expenses mainly include mining machines, site and electricity costs. The breakeven point of mining using the Bitland Ant Ant S9 is about $7,000.
