Bitcoin miners may catch another break this week as the network’s mining difficulty is estimated to see a reduction tomorrow. Every two weeks Bitcoin’s difficulty adjustment algorithm (DAA) changes, and during the last DAA change, the difficulty dipped by 4.33%. Currently, at 235 exahash per second (EH/s), the network is expected to see a DAA reduction of 0.51% from today’s metric.
This Week’s Bitcoin Mining Difficulty Change Is Expected to Drop Lower
On June 7, 2022, there’s one more day until the next DAA change and it’s expected to drop lower when the shift commences. The DAA changes every 2,016 blocks or roughly every two weeks, and after block height 735,840, it was the highest difficulty rating ever recorded at 31.35 trillion.
Essentially, if blocks are mined quicker than expected, the DAA increases and if the blocks mined were slower during the two-week period, the difficulty decreases. After the all-time high (ATH) at 31.35 trillion, the last DAA shift at block height 737,856 dropped by 4.33%, bringing the current difficulty parameter down to 29.90 trillion.
When the difficulty drops, it is a lot easier to find bitcoin block rewards, and when the DAA metric increases, it is a lot harder for bitcoin miners to find BTC block rewards. The DAA retarget is more than 160 blocks away and is expected to change tomorrow, June 8, 2022.
If the expected 0.51% drop comes to fruition, the difficulty will be 29.75 trillion for two weeks following the DAA change. Bitcoin’s hashrate has been running at a fast pace after reaching an ATH of 275 EH/s on May 2, but since then it has not run higher than the lifetime record. In fact, as the price slipped lower toward the end of May, the hashrate had temporarily dipped under the 200 EH/s zone.
While a DAA shift downward is expected, during the last three days, 445 BTC block rewards were mined into existence. Foundry USA captured the most blocks during the past three days, as it found 105 out of the 445 BTC block subsidy rewards.
Foundry’s hashrate represents 23.6% of the global hashrate or 49.70 EH/s of processing power. Antpool is the second largest mining pool in terms of hashrate as the pool snagged 78 block rewards during the 72-hour period. Antpool has 36.92 EH/s dedicated to the BTC blockchain, which equates to 17.53% of the global hashrate.
There are 14 known pools dedicating hashrate to the BTC chain and 0.45% of the global hashrate or 946.74 petahash per second (PH/s) belongs to unknown or stealth miners. Profits have dropped a great deal, as the most powerful ASIC mining device, Bitmain’s Antminer S19 Pro+ Hyd. with 198 terahash per second (TH/s), gets an estimated $9.80 per day.
That figure includes paying $0.12 per kilowatt-hour (kWh) and the current difficulty at 29.90 trillion. The Microbt Whatsminer M50S with 126 TH/s and electrical costs at $0.12 per kWh, can make an estimated $6.78 per day in BTC profits. Many of the ASIC mining devices manufactured before 2021 are making $5 or less per day in profits, at current BTC exchange rates.
