Bitcoin could be 'game changer' for investment

Bitcoin, a virtual currency, may be a game changer for overseas investment as many Chinese are using it to snap up properties in Europe, insiders said.

But legal experts warned of a bubble about to burst due to a lack of confidence in the digital currency and further regulations.

"It is definitely a trend, because I don't see why people can't do it, since it is an easier and quicker way to invest overseas," said Bobby Lee, chief executive officer and co-founder of BTC China, one of the world's largest bitcoin exchanges, on Tuesday.
