​Bitcoin slumped 7 per cent to near US$35,500, recalling levels seen in the crypto meltdown last week as traders brace for fresh volatility over the long weekend.

Prices across digital tokens took a hit as Bank of Japan Governor Haruhiko Kuroda joined a growing list of central bankers expressing skepticism about the industry’s usefulness in the real world.

Now, retail players are set to dominate the coming trading sessions on typically thin exchange volumes.

“Looking at the unrest across the crypto market, there is a chance that we see another hectic weekend trading in Bitcoin and other cryptocurrencies,” said Ipek Ozkardeskaya, a senior analyst at Swissquote.

Prices spiked 10 per cent last Saturday, only to plunge by 18 per cent the next day.

“Most of the trading is speculative and volatility is extraordinarily high,” Kuroda said in an interview Thursday. “It’s barely used as a means of settlement.”

All the same, Bitcoin was little changed for the week, after a 44 per cent selloff from the April’s peak of US$63,000.

More broadly, the threat of tougher regulation continues to be a drag on crypto market sentiment. China and Iran have cracked down on Bitcoin mining operations for using too much electricity and there’s speculation that the U.S. policymakers may increase financial oversight given the market’s growing size and intense volatility.

On a technical level, the key marker is US$30,000, said Swissquote’s Ozkardeskaya. A break below that level would be “further affirmation of an extended bear market,” she said.

“Volatility has eased this week, but that probably won’t last entering a long weekend,” Edward Moya, senior market analyst at Oanda Corp., wrote in a note. “Bitcoin’s consolidation phase should continue, but if the US$37,000 level breached momentum, it could get ugly fast.”
