Bitcoin‘s mining difficulty rose roughly 3.4%.
The move was modest compared to the 13% increase from earlier this month.
The mining difficulty automatically adjusts every 2016 blocks, occurring roughly every two weeks. The difficulty exists to ensure that transactions process at a steady pace regardless of how high or low the network Hash rate is at a given time.
The Bitcoin Mining hash rate hit an all-time high of 266 EH/s this month. The current network hash rate was roughly 263 EH/s as of Saturday.
According to the most up-to-date estimate, miners have generated roughly $420 million in revenue thus far this month.
