The computing power of the special bitcoin mining machine in Chinese mainland is only 100 power, and only11500 bitcoins can be dug in one day, so it takes100 ÷11500 =/kloc to dig one.

Computing power is an index to measure the processing power of bitcoin network, also known as hash rate. When the network reaches the hash rate of 1 times/second, it means that 1 trillion calculations can be made every second.
