The U.S. has overtaken China as the largest bitcoin center after Beijing tamped down on cryptocurrency mining in recent months.

At the end of August, the U.S. controlled 35.4 percent of the global hash rate — the power of computers connected to the global bitcoin network — the largest percentage of all countries, according to data published on Wednesday by Britain’s Cambridge Centre for Alternative Finance and cited by Reuters.

Kazakhstan and Russia had the second- and third-largest hash rates, respectively, according to Reuters.

China’s hash rate dropped significantly over the past few months, falling from 44 percent in May to zero in July, Reuters reported. In 2019, it had reached as high as 75 percent.
