On Monday, bitcoin was trading at $2,179, down $612 from last Wednesday's all-time high of $2,791, according to CoinDesk data.

"The correction was actually quite brief, the prices today are still higher than that of a week ago," Bobby Lee, CEO of BTCC, a major bitcoin exchange, told CNBC.

"I think the pullback was just a profit taking, a correction from the skyrocketing prices of last week," he added.

Bitcoin's market cap fell from $40.49 billion on Thursday to $36.48 billion.

Analysts' forecasts for bitcoin differ significantly. While some predict a major correction, others say it's going to hit $6,000.

"There is a lot of fresh liquidity flowing into bitcoin, thanks to a surge in interest among investors in Asia, notably Japan and Korea, coupled with a resolution to the scaling debate. I would not be surprised to see the bitcoin price doubling again to around $6,000 by the end of the year," Aurelien Menant, CEO of Gatecoin, a regulated cryptocurrency exchange, told CNBC.
