Bitcoin’s mining difficulty level rose 3.4% on Thursday to an all-time high, as the network’s hashrate also increased to a record high. The difficulty level changes roughly every two weeks and measures how hard a miner would have to work to verify transactions on a block. A higher difficulty reading indicates that it is more competitive to mine Bitcoin, reducing the profitability for miners.

- The mining difficulty reading came in at 51.23 trillion at block height 792,288 in Thursday’s adjustment. That follows a 3.22% rise in the previous adjustment on May 18, according to data from BTC.com.
- The difficulty of mining Bitcoin typically rises when more miners go online, which raises competition. Miners are rewarded Bitcoin for validating transactions on the network. The higher the difficulty, the less chance a miner has to secure an entire block on the chain. Therefore, a miner’s profitability is dependent on the difficulty level.
- Mining difficulty adjustments are closely correlated to changes in hashrate, the level of computing power used for mining.
- Bitcoin’s hashrate was at around 375 exahashes per second on Wednesday. That was an increase from the 365.1 exahashes recorded during the last adjustment on May 18, data from Blockchain.com shows.
- At that time Bitcoin was trading at around US$26,800, up roughly 61% for the year. Its price stood at US$27,068 at 10:10 a.m. in Hong Kong on Thursday. That was a rise of 3.6% for the past seven days, according to data from CoinMarketCap.
- Meanwhile, most Bitcoin mining-related stocks in the U.S. gained this week. On Sunday, Republican congressman Warren Davidson indicated that a proposed tax on electricity use by cryptocurrency miners in the country had been scrapped. The decision is part of the ongoing U.S. debt ceiling negotiations between the White House and House Republicans.
- Shares of cryptocurrency mining company Marathon Digital Holdings on Nasdaq have climbed 9.6% since closing on Friday — a rise of 187.9% for the year. Bitcoin miner Riot Platforms shares have also jumped 9.9% since Friday — a 256% rise since the beginning of this year.
