During the last 90 days, Bitcoin’s hashrate has been climbing
higher and has been slowly nearing the all-time high (ATH) the network
captured six months ago in May. The accelerated hashrate has caused the
network difficulty to rise, as Bitcoin’s mining difficulty has adjusted
upward nine times in a row to date and it’s closing in on the network
difficulty ATH recorded six months ago.
Bitcoin’s Mining Difficulty Approaches Lifetime High
Bitcoin’s mining difficulty is approaching the all-time high recorded
on May 13, 2021. The network’s difficulty is basically a mechanism
Satoshi Nakamoto added to maintain a steady rate of close to ten-minute
blocks. Furthermore, the difficulty also makes the entire system
stronger security-wise, as a 51% attack becomes a lot more expensive and
far more difficult to achieve.
When the hashrate changes, every two weeks, the network takes the
change into account, and when the hashrate increases the difficulty to
mine bitcoin (BTC) also rises. When the hashrate experiences a sudden dive, like it did at the end of June and during the month of July over the bitcoin mining crackdown in China, the difficulty will also lower. When BTC’s hashrate plummeted this year, the network’s mining difficulty slid by 39.8% in different intervals.
Difficulty Needs to Increase More Than 10% in Order to Capture New Record High
The difficulty’s ATH on May 13, 2021, was roughly 25.05 trillion, and
two weeks later it adjusted down to 21.05 trillion. Following July 3, BTC’s
mining difficulty slid to a low of 13.6 trillion after it experienced
the largest downward difficulty adjustment in the network’s lifetime.
That massive downward drop was approximately 27.94% at block height
689,472. Today, BTC’s mining difficulty is 22.67 trillion and getting awfully close to nearing its 25.05 trillion ATH.
mining difficulty is currently 22,674,148,233,453 on November 20, 2021.
The all-time high was 25,046,487,590,083 in mid-May 2021.
The bottom line is bitcoin (BTC)
will be more difficult to mine than it was six months ago in a short
period of time. The mining difficulty will need to increase by 10.27%
from the current position to surpass the May 13 record high. At current
SHA256 profitability rates, the odds of BTC’s
mining difficulty increasing enough to surpass the difficulty ATH
recorded six months ago is far greater. ASIC bitcoin mining rigs such as
the Microbt Whatsminer M30S++, Ipollo’s B2, and the Bitmain Antminer
S19 Pro still make over $25 per day paying $0.12 per kilowatt-hour (kWh)
in electricity costs.
