A massive spamming attack led more bitcoin exchanges to halt trading.
The distributed-denial-of-service attack involved thousands of phantom transactions, forcing at least three of the online platforms that store bitcoins and trade them for traditional currencies to halt withdrawals of bitcoins until they can determine which transactions were real.
Bitcoins slumped in value as a result of the disruptions.
"Bitcoin is still an experimental protocol in its infancy," said Micky Malka, a venture capitalist who is on the board of Bitcoin's trade group, the Bitcoin Foundation.
"It will grow and mature over time," he added. "No one should be investing an amount they cannot afford to lose."
