Bitcoin, The hash rate surged to an all-time high of 398 terahashes per second (TH/s) on March 23, with analysts speculating that miners started turning their machines back on as BTC prices rose.
According to data aggregator YCharts, the bitcoin network hash rate fell to 344.63 TH/s as of March 27 from 335.32 TH/s on March 26, but remains higher than the 178.77 TH/s a year ago.
In a March 26 post, Sam Wouters, a research analyst at bitcoin financial services provider River Financial, speculated that the surge in hash rate was linked to unused mining inventory coming online, new facilities coming online, and entrepreneurs looking for cheap mining resources. “While the price of bitcoin was so low last year and as much inventory as possible was brought online, at some point, the maximum capacity the network could handle was reached,” he said. "Now that prices are rising again and some time has passed, more stock has been able to come online," Wouters added.
Additionally, Hydro models are starting to hit the market with “250+ TH/s per machine, which adds up to a huge hashrate,” Wouters said. A March 20 analysis by investment banking firm Stifel echoed a similar sentiment, speculating that the recent spike may have something to do with miners bringing their hardware back online.
“We expect the overall network hash rate to continue to climb as well-capitalized miners purchase attractively priced hardware.” Nazar Khan from bitcoin mining company TeraWulf explained that the company is currently maximizing the hash rate of all its miners and has recently added more miners to its new Nautilus Cryptomine facility.
“Wulf has the opportunity to add 80 MW of capacity and 50 MW of capacity at LMD and Nautilus. Recent price action demonstrates the long-term value of expanding capacity at low-cost energy sites,” Khan said. According to Khan, while some have speculated that lower prices forced miners to shut down their rigs and wait for BTC prices to rise, TeraWulf was able to continue mining Bitcoin at lower price levels because they were losing money from their "efficient mining fleet." costs.
However, whatever the reason for the surge, Khan said TeraWulf does not expect the network hashrate to continue increasing in the first half of the year, regardless of BTC prices. “There is a lag between investment decisions being made and capacity coming online,” Khan explained.
