Bitcoin fell below $30,000 for the first time since Jun. 22 on Monday dragging other digital coins lower.

Bitcoin was down nearly 6% while ether fell 8% and XRP tanked almost 10%, according to CoinDesk data.

The plunge in bitcoin came after a big sell-off in global stock markets. On Monday, the Dow Jones Industrial Average had its worst day since last October.

“There’s been a broad sell-off in global markets, risk assets are down across the board,” Annabelle Huang, partner at cryptocurrency financial services firm Amber Group, said.

There are “concerns of the quality and strength of economic recovery” and “broader risk assets turned weaker including high yields,” Huang said. “Coupled with recent BTC (bitcoin) weakness, this just sent crypto market down further.”

Since bitcoin’s all-time high of nearly $65,000 in mid-April, its price has plunged over 50%.

Major regions responsible for bitcoin mining in China have forced operations to shut down. Bitcoin mining is an energy-intensive process that facilitates bitcoin transactions and creates new coins.

China’s central bank has also spoken to finance and fintech companies reminding them not to offer crytpo-related services to customers.

China banned local cryptocurrency exchanges in 2017 forcing them to move offshore. That did not stop Chinese traders buying and selling digital coins. But the tough actions this year from Chinese regulators has looked to further tighten restrictions on trading and mining.
