Bitcoin’s global network appears to be recovering from the recent slump caused by China's crackdown on the crypto mining industry.
According YCharts, the hash rate reached 115.71 EH/s on July 27, and even though it dropped to 106.7 EH/s the next day, it nonetheless marks an 82.5% increase since the steep decline to 58.46 EH/s seen a month earlier.
Bitcoin’s hash rate—the measuring unit of the network's processing power—hit an all-time high above 198 EH/s in mid-April.
However, over the next two months it declined sharply, after the authorities in several Chinese provinces issued shutdown orders against Bitcoin mining operators, forcing them to relocate to countries including the USA and Kazakhstan.
The increase in hash power is also set to result in Bitcoin's mining difficulty going up in two days' time, when the next adjustment of the parameter will occur.
Mining difficulty is a measure designed to calculate how much computational power is required to produce new Bitcoin; the fewer miners are online, the easier mining Bitcoin becomes.
Bitcoin mining difficulty peaked above 25 trillion in mid-May. However, since then it has become as much as 54% easier to find new blocks.
Slow but steady recovery
Some experts believe that Bitcoin’s network is now well on the way to recovering from the slump, even predicting a new all-time high in mining difficulty (with the caveat that it's not going to happen in the next couple of months).
“In the short-term perspective, over the next difficulty adjustments for the rest of the year, we can expect a slow and steady increase in the global network hash rate and, thus, an increase in Bitcoin mining difficulty,” Edward Evenson, head of business development at Braiins, the operator of Slush Pool, told Decrypt.
That's down to next-generation mining machines from Bitmain and MicroBT starting to be delivered to miners.
Meanwhile, miners that already have a significant amount of existing capacity will be turning on more machines. However, Evenson reckons that this will be a protracted process due to the mass exodus of machines and hash rate out of China over the last several months.
“It will be some time before these machines are turned on and we return to an all-time high in terms of global hash rate," said Evenson, who added that a new all-time high will probably occur "some time in Q1 or Q2 next year.”
