According to Global Trends in their GT Briefing December 2012: Trends to watch in 2013, they mention BitCoin as an alternative to cash under “Who needs Banks anyway?” section of their report.  This along with Mobile-wallets and Crowdfunding, are definitely things to keep close tabs on as I suspect they will gain significant traction to in 2013.

The Global Trends to watch in 2013 are:

1. Social everything: New generations and their digital world stepping forward
2. Redefining value: The consumer is winning the fight to own the new consumer
3. Distributed everything:  Mobility in production and consumption
4. The next “industrial” revolution: Robots and smart machines reshaping work
5. The new space race: Pushing the frontiers of technology once again?
6. Geopolitical wars: The fight to control the future
7. Resource wars escalating: From a world of abundance to shortage
8. Business stepping up:  From profit to purpose
9. Information is power: The security challenge
10. Who needs banks anyway? Reshaping the financial system
