The difficulty is adjusted every 2016 blocks based on the time it took to find the previous 2016 blocks. At the desired rate of one block each 10 minutes, 2016 blocks would take exactly two weeks to find. If the previous 2016 blocks took more than two weeks to find, the difficulty is reduced.
How often does Bitcoin difficulty adjust?
The difficulty rate automatically adjusts on a fortnightly basis to maintain consistent block times of around 10 minutes per block; this ensures blocks are added at regular intervals into Bitcoin’s blockchain.
Can Bitcoin difficulty decrease?
Bitcoin’s mining difficulty adjustment occurs every 2,016 blocks, or about every two weeks, as Bitcoin is programmed to self-adjust in order to maintain a target block time of 10 minutes. … The ongoing difficulty drop falls in parallel with declining Bitcoin hashrate as well as decreasing average BTC transaction fees.
Why is bitcoin block time 10 minutes?
Ten minutes was specifically chosen by Satoshi as a tradeoff between first confirmation time and the amount of work wasted due to chain splits. After a block is mined, it takes time for other miners to find out about it, and until then they are actually competing against the new block instead of adding to it.

The difficulty adjusts every 2016 blocks. Approximate number of blocks per day is: 6 blocks per hour X 24 hours = 144 blocks. 2016 blocks / 144 blocks per day = 14 days. Approximately every two weeks the difficulty adjusts.
Why does ethereum difficulty increase?
Ethereum mining difficulty determines how difficult it will be to mine the next block and this is why it is referred to as the difficulty of Ethereum mining. … As more hashing power is added to the Ethereum mining network, the difficulty must increase to ensure blocks are not being generated too quickly.
