I need a little help from my bitcoin friends!

Should bitcoin be treated as a currency or as an investment asset? And what could contribute to a wider usage of bitcoin as a currency?
These are questions I would like to answer in my master thesis.

Please give me some insights into your bitcoin user habits by answering this short survey (should only take 6-10 minutes to complete):
