Bitcoin Mining Difficulty Hits Record With Pressure Mounting on Profit Margins
- Miners compete to solve cryptographic puzzles to win rewards

Mining difficulty inched up 3.5% on Wednesday, according to data from crypto-mining tracker CoinWarz. The measure, which has been climbing steadily over time, tends to mirror expectations for directional price changes. Bitcoin has dropped about 10% in the aftermath of a software code adjustment in April known as the halving that slashed by half the possible revenue available to miners, pressuring the margins of many of the companies.
