Sparkpool, the second-largest Ethereum mining pool in the world, is suspending operations due to the ongoing Chinese crackdown on crypto. The mining pool officially announced that it has suspended access to new users in mainland China on Monday in response to Chinese authorities initiating new measures to combat crypto adoption in the country. Following the initial restrictions made last Friday, Sparkpool will continue shutting down services, and plans to suspend existing mining pool users both in China and abroad on Thursday.
