Mining difficulty can also change if more machines participate in mining. The more online mining, the mining hashrate will increase, so the mining difficulty will also be increased. If there are fewer miners online, the hashrate will decrease, so mining difficulty will also decrease. Mining difficulty is set every 2,016 blocks or on average about once every 2 weeks.

Mining Difficulty is also closely related to the cost of electricity and the market price of Bitcoin to pay for electricity. The more difficult it is to do hashing, the miner’s electricity cost will also be higher.

With mining difficulty, the Bitcoin network will continue to run even if the number of miners decreases. And the Bitcoin network will always be safe regardless of how many miners are involved in the mining process.
