Bitcoin’s hashrate had been rising exponentially from 2009 through mid-2018, increasing through the megahash (M/H), gigahash (G/H), terrahash (T/H), petahash (P/H), and exahash (E/H) ranges. The hashrate first exceeded 60 EH/s in August 2018, and then the exponential increase gave way to stabilization.
In September and October 2018, the hashrate remained stable, averaging above 50 EH/s, simultaneous with the price of Bitcoin being stable near $6,500. Then the price of Bitcoin plummeted starting in mid-November to as low as $3,100 in December. The hashrate of Bitcoin collapsed to 32 EH/s during this market crash, implicitly indicating 20-30 EH/s being forced offline due to a lack of profitability, which represents billions of dollars of equipment.
However, the collapse in hashrate may be coming to an end, at least for now, due to the price of Bitcoin rising back to the $4,000 level combined with a 29 percent decrease in mining difficulty.
As can be seen in the chart, Bitcoin’s hashrate appears to have stabilized in December, breaking the trend of constant decline.
There are two factors that are bringing about stabilization. First off, the price of Bitcoin has stopped decreasing and has risen back to where it was at the beginning of December near $4,000. A stable Bitcoin price is a necessary ingredient for a stable hashrate.
More importantly, the mining difficulty of Bitcoin has dropped from 7.184 trillion to 5.106 trillion, a 29 percent decline, which makes Bitcoin mining 29 percent more profitable per unit of hashrate. As long as price does not continue to fall Bitcoin will find an equilbrium hashrate since difficulty adjusts downwards as miners turn off their rigs. The point at which the difficulty stops adjusting downwards is the equilibrium point, a steady state where the existing hashrate can profitably mine or break even without the loss of further hashrate.
Currently ,Bitcoin’s hash rate is near 36 EH/s, which would yield a 2.6 percent increase in difficulty if the difficulty re-adjustment happened now. This suggests that the equilibrium level for Bitcoin’s hashrate, at least at the current Bitcoin price of $4,000, is right around the current hashrate.
That being said, the price of Bitcoin going up or down can rapidly change the situation. If Bitcoin retraces back towards $3,000, then the hashrate is likely to fall further, and if it rallies strongly then the rigs that were turned off would quickly be switched on again.
The fact that there are 20-30 EH/s of rigs shutoff makes the future a bit gloomy for Bitcoin miners, since increases in Bitcoin’s price will not lead to higher profits for miners until all of those rigs are switched back on.
There used to be a lag effect between Bitcoin’s price rise and the switching on of new rigs, which allowed miners to make bigger profits before difficulty adjusted upwards. Until the hashrate exceeds 60 EH/s, the time it takes to switch on the dormant rigs will be instant, whereas before miners had to wait weeks or months to order rigs and then switch them on. Based on the data, Bitcoin would probably have to be at $7,000 or higher before Bitcoin miners start seeing increased profit margins.
Looking at the broader picture though, it is certainly good news that the Bitcoin mining hashrate has stopped going down since this means Bitcoin will continue to be extremely secure and decentralized. A rapidly dwindling hashrate would make Bitcoin less secure and more centralized, two factors that would threaten Bitcoin’s reputation.

Die Hashrate des Bitcoin-Netzwerks ging nach Angaben von Ethan Vera vom Luxor Mining Pool um etwa 20 % zurück. “Seit der Halbierung ... Of course, the Bitcoin Energy Consumption Index is also very much a prediction model for future Bitcoin energy consumption (unlike hashrate-based estimates that have no predictive properties). The model predicts that miners will ultimately spend 60% of their revenues on electricity. At the moment (January 2019), miners are spending a lot more on electricity.

More about this chart. Explanation. Mining hashrate is a key security metric. The more hashing (computing) power in the network, the greater its security and its overall resistance to attack. Although Bitcoin’s exact hashing power is unknown, it is possible to estimate it from the number of blocks being mined and the current block difficulty. Notes. Daily numbers (raw values) may ...
