Bitcoin Hash Rate Resumes Uptrend, Poised to Retest 400 TH/s All-Time High
The Bitcoin hash rate continues its upward trajectory, following a spike recorded over the weekend of May 27-28, 2023, that places it on track to retest its all-time high of 400 TH/s.

The hash rate quantifies the computing power within a Proof-of-Work (PoW) network. It also serves as a key indicator for gauging the overall health and security of the network.
A higher hash rate indicates increased attempts to solve the target hash and win block rewards, signaling either more miners participating in the network or the deployment of more powerful mining equipment.
Bitcoin hash rate
The chart above illustrates the sustained upward trajectory of the Bitcoin hash rate. Although a temporary decline occurred around May 2021 due to the ban on PoW mining in China, a recovery beginning in late June 2021 marked a notable acceleration in the overall upward trend.
In March, members of the Bitcoin community commented on the unprecedented rise in hash rate, offering various theories to explain the phenomenon.
Seb Gouspillou, CEO of mining firm BigBlock DC Bitcoin, attributed the surge to a wave of miners upgrading outdated equipment. Conversely, Sam Wouters, an analyst at River Financial, linked the jump in hash rate to positive BTC price action, which saw the leading cryptocurrency spike from $22,000 to $28,300.
In March, the hash rate reached a new all-time high of 398 TH/s. After a brief decline, it surpassed this level on May 11, hitting 400 TH/s. Three weeks later, the hash rate is shaping up to retest this level, with a current reading of 396 TH/s.
Difficulty adjustment
An ongoing debate exists regarding whether the Bitcoin price follows the hash rate or if the relationship is the other way around.
Will Clemente, co-founder of Reflexivity Research, hinted at the former by pointing out that during the 2019 bear market, the hash rate did not reach an all-time high until Bitcoin tripled in price from its lows. In the current cycle, the hash rate has doubled from its May 2021 lows, yet the BTC price has increased by only 75% from its low.
Similarly, Max Keiser, host of the Orange Pill Podcast, stated, “Hashrate is more important to follow than price,” adding that the price has a “mathematically guaranteed” higher probability of increasing alongside a rising hash rate.
CryptoSlate Researcher James Van Straten noted that the rising hash rate would warrant a difficulty adjustment upward. However, since 2020, the summer period has typically been characterized by lower difficulty adjustments—a pattern that has not occurred this year.

Mining difficulty refers to an algorithmic function that regulates the timing of block solving. For instance, a rising hash rate reduces the time required to solve the target hash, but since block time must remain around 10 minutes, the difficulty must adjust higher to compensate.
