The last two mining difficulty changes on the Bitcoin network have pushed the difficulty to an all-time high, resulting in a reduction in hashrate and block interval speed. Before the latest 4.68% increase in retargeting difficulty, block intervals were faster than the 10-minute average, at approximately 8 minutes 54 seconds to 9 minutes 31 seconds. However, since the change, block times have slowed, with statistics showing durations ranging from 10 minutes 44 seconds to 10 minutes 36 seconds.
Below-average block intervals can lead to a drop in Bitcoin mining difficulty
The next mining difficulty change is scheduled for February 12, 2023. At the time of writing, the metrics suggest that the difficulty could go as low as possible 5.6% below the current course. The drop in estimated mining difficulty for Bitcoin is due to below-average block intervals. Before the last two difficulty increases, block times were faster, which led to the increases. Currently, data shows that block times have slowed since the last difficulty change, with times ranging from 10 minutes 44 seconds to 10 minutes 36 seconds.
Bitcoin's hashrate has been below average, averaging 279 exahash per second (EH/s) over the last 2,016 blocks. As of 11:30 a.m. ET on February 4, 2023, statistics show the hashrate at 258 EH/s. On February 1, 2023, the total hashrate fell to 217 EH/s after reaching a high of 279 EH/s the previous day. The hashrate then increased, reaching 309 EH/s on February 2nd before declining by 16.50% to its current level 258 EH/s.
As of Saturday, Foundry USA is the top Bitcoin mining pool 90.61 Exahash per second (EH/s) or 33.4% of the total hashrate. Foundry is followed by Antpool (18.14%), F2pool (14.08%), Binance Pool (13.13%) and Viabtc (9.07%). Thirteen known Bitcoin mining pools contribute to the blockchain, while unknown miners known as stealth miners control 1.67% of the hashrate or 4.53 EH/s. If slowing block intervals results in a decrease in difficulty in eight days, miners will get a two-week reprieve from the all-time high difficulty.
