Why China’s Crackdown May Make Bitcoin Mining More Centralized

China’s nationwide crackdown on crypto mining could create a competitive environment in which only the biggest miners can survive, said a co-founder and managing partner of Waterdrip Capital, a major investor in the Chinese crypto mining industry. “Finding suitable sites outside the mining hubs requires a lot of resources such as capital and network,” Yusan Zheng said during a Chinese-language Clubhouse discussion hosted by CoinDesk. “Only the most experienced and deep-pocketed miners will be able to carry out such a plan.”

Local authorities in major Chinese mining hubs have started banishing crypto mining businesses since last Friday’s crackdown notice from the State Council. With little idle capacity in overseas hosting sites, some miners plan to go underground and continue to operate in other parts of the country, which might be only feasible for some of the biggest miners. If mining power is too centralized, a few miners could manipulate the market by controlling the supply of bitcoin, or rewrite transactions on the immutable distributed ledger in the bitcoin network and shut out smaller miners with over 50% of the network’s mining power.

Chinese mining firms have also been trying to find overseas hosting sites since the crackdown. But major global mining hubs such as Kazakhstan and Russia have little to no idle capacity to support new machines. Mining farms in North America are expanding their operations but that will take a long time to reach sufficient capacity to host the majority of Chinese miners’ mining machines, according to Ethan Vera, chief operating officer at Luxor. “It is impossible to move all of the mining machines in China abroad,” Zheng said. “Miners have to figure out a way to keep the machines running.”
