The price of bitcoin rose above $43,000 for the first time since May.
As of press time, the largest cryptocurrency by market value was changing hands at around $42,901, up 4.9% over the past 24 hours.
The latest rally took bitcoin’s year-to-date return to 48%, far exceeding the Standard & Poor’s 18% gain.
Cryptocurrency traders and analyst say a risk-taking mood has returned to digital-asset markets after a bear market that saw prices fall below $30,000 from an all-time high in April near $65,000.
