Ed Wray knows a fair bit about the internet. Having worked at JP Morgan for eight years he co-founded of Betfair in 1999, where he served as chairman until March 2012.

He went on to become a non-executive director at crowdfunding site Funding Circle and to invest in taxi app Kabee.

We caught up with Wray at the launch event for the International Festival for Business at the London Stock Exchange to talk Bitcoin, crowdfunding and see if the Kabee investor still likes to take the tube.
