Bitcoin’s phenomenal rise in 2017 has been due to a couple of factors, from a surge in media and online chatter to interest from Asian and institutional investors. (See also: Why Bitcoin Is The Ultimate Value Play.) For example, Japan and South Korea are among the top three trading venues for cryptocurrencies. In terms of trading volume, the Japanese yen accounts for approximately 61% of overall trading volume in bitcoin while the South Korean Won is responsible for 11 percent.

Hedge funds catering exclusively to the cryptocurrency space have also multiplied recently. Exchange powerhouse CME is expected to begin bitcoin futures trading towards the second week of December.

While interest from institutions has driven bitcoin prices higher, some investors have already begun warning about a bitcoin bubble. Billionaire Michael Novogratz, who has invested roughly 10% of his fortune in cryptocurrencies, told audiences at a conference yesterday that bitcoin was the “biggest bubble” of our lifetime.

“This is a bubble and there is a lot of froth,” Novogratz said. Still, that froth doesn’t seem to have dissuaded Novogratz from predicting prices of $40,000 for the cryptocurrency by the end of 2018. (See also: Bitcoin Bulls And Bears Square Off In New York.)
