Bitcoin’s (BTC) network hash rate dipped a record 40% yesterday, Sept. 23, in a sudden shock for the network.

Data from Coin.dance — corroborated by other sources [insert links] — indicates that the network’s hash rate plummeted yesterday from over 98,000,000 TH/S to 57,700,000 TH/s.
Mystery flash crash remains unexplained
The flash drop remains unexplained as of press time and is all the more striking given the Bitcoin network’s record-breaking string of new all-time high hash rates throughout summer.
Bitcoin’s hash rate had passed a record 102 quintillion hashes in a historic milestone.
As previously noted, the hash rate of a cryptocurrency — sometimes referred to as hashing or computing power — is a parameter that gives the measure of the number of calculations that a given network can perform each second.
A higher hash rate means greater competition among miners to validate new blocks; it also increases the number of resources needed for performing a 51% attack, making the network more secure.
By press time, Bitcoin’s hash rate has somewhat recovered back to almost 88,300,000 TH/s — yet remains well below its earlier records.
Throughout summer, cryptocurrency analysts had argued that the network’s record-breaking streak of all-time hash rate highs was a bullish indicator for the top coin’s price performance.
In a tweet posted this August, Bitcoin investor Max Keiser had claimed that:
“Price follows hashrate and hashrate chart continues its 9 yr bull market.”
Back in November 2017, Bitcoin had seen a sudden hash rate downturn of almost 50%, accompanied by slowed transaction processing times, a price dip, and even miners’ short-lived switch over to the forked network, Bitcoin Cash (BCH).
