Following the largest mining difficulty drop in Bitcoin’s history, this weekend will once again see another slide, but less than 5% of the difficulty will be shaved. Statistics show Bitcoin’s hashrate has been able to climb higher since the difficulty drop two weeks ago, and climbed above 100 exahash per second (EH/s) this week. This weekend’s upcoming bitcoin mining difficulty drop will be the only time in history the difficulty slipped four times in a row.

2021’s Consecutive Difficulty Drops Surpass 2011’s Records

After China cracked down on bitcoin miners at the end of June, a large quantity of hashpower had temporarily halted. Statistics indicate that the hashrate was around 66 EH/s on June 28 and since then it has increased to above the 100 EH/s zone.

There’s currently 18 known mining pools dedicating hashrate to the BTC chain, and 4.71 % of the global hashrate (24-hour stats) or 4.79 EH/s belongs to unknown miners.

This weekend, Bitcoin’s mining difficulty will drop for the fourth time in a row losing 54%. Bitcoin’s mining difficulty has never dropped four times in a row, but did drop three times consecutively in 2018.

Two weeks ago the Bitcoin network saw the largest difficulty drop ever and another difficulty drop is expected this weekend. Using today’s average hashrate, statistics show the drop will be less than 6% bringing the current difficulty of 14.36 trillion down to 13.5 trillion.

This means after the dip, the mining difficulty will have dropped four times in a row. The last time the BTC mining difficulty dropped more than four times in a row was in 2011. From August to November 2011, the mining difficulty dropped eight times in a row.

2018 Saw Three Difficulty Drops in a Row, Five Mining Pools Currently Command 59% of Bitcoin’s Hashrate

The only other time BTC’s mining difficulty came close to the four times in a row record was in 2018 for three consecutive difficulty drops between November and December.

August to the end of November 2011 saw eight consecutive difficulty drops in a row.

The most recent number of difficulty drops will see 54% shaved off the difficulty, which is slightly higher than the 51.54% shed in 2011. This means 2021’s consecutive downward difficulty adjustments were the greatest so far. Back then, the difficulty tapped a high of 1.89 million in August and by November it was 1.09 million at block height 155,232.

At the time of writing, the top mining pools on Friday afternoon include Viabtc, Antpool, Poolin, F2pool, and Btc.com. These pools are followed by Binance, Foundry and Slushpool, but the top five operations command 59.4% of the global hashrate.

Binance, Foundry and Slushpool capture 21.9% of BTC’s hashpower on Friday afternoon. That leaves ten known pools and 4.79 EH/s of unknown hashpower, commanding 18.7% of the global hashrate.
