The slump for bitcoin continued on Tuesday morning as the leading cryptocurrency fell below a key level and is trading at its lowest price since January.

Bitcoin was down 8% to $29,674.25, according to Coin Metrics. Traders had warned a break below $30,000 could lead to more losses.

Technical analysts had been watching the $30,000 level as a key support level on the charts after the cryptocurrency had fallen to near that low during its May crash. The analysts, who study charts to make buying and selling decisions, believe the next level to watch for support could now be as low as $20,000.

Now that it is approaching $29,000, the price of bitcoin is threatening to turn negative for the year.

Galaxy Digital CEO Mike Novogratz said on CNBC’s “Squawk Box” that bitcoin could still rebound after Tuesday’s move but there was significant downside to the next support level.

″$30,000, we’ll see if it holds on the day. We might plunge below it for a while and close above it. If it’s really breached, $25,000 is the next big level of support,” Novogratz said. “Listen, I’m less happy than I was at $60,000 but I’m not nervous.”

Bitcoin has been struggling to reclaim its highs from earlier in the quarter. It fell dramatically in May following some market-moving tweets by Elon Musk about bitcoin-related environmental concerns, and then even further in early June around fears of the cryptocurrency’s use in the Colonial Pipeline ransomware attack.

It’s been on a rollercoaster ride since then, battered by a stream of headlines out of China, where regulators have imposed new restrictions on energy-intensive mining and ordered financial institutions like Alipay to stop doing business with crypto companies. The price briefly touched $40,000 last week and fell again Monday.

With Tuesday’s losses, bitcoin has slid about 54% from its all-time high of more than $64,000 in mid-April, taking other cryptocurrencies along with it. Ether fell 8% and dogecoin is dropping more than 16%.

Significant pullbacks have happened before in the cryptocurrency market, with bitcoin falling about 80% from its late 2017 highs at one point. Professional crypto investors have warned that the space should continue to be volatile in the years ahead.

“The only guarantee with the cryptocurrency space is volatility and obviously, that’s what we have right now,” Fairlead Strategies founder Katie Stockton told CNBC. “It’s not new, we’ve had days like this before, it’s just a matter of navigating through this noise.”

Novogratz also noted that despite previous pullbacks, crypto market infrastructure is only becoming more mature, which has helped usher in more institutional support over the past year, with major hedge fund managers, pension funds and banks jumping into crypto, while registered investment advisors seek ways to get clients exposure to cryptocurrencies in a way that’s compatible with their current workflow.

The price of bitcoin rose nearly 500% between mid-September of last year and its April peak. Even with the recent decline, the cryptocurrency is still up about 150% over the past 12 months.
