Definitely Business, there are just way too many advantages to Bitcoin to ignore it.
My secondary reasons include:

. Truly international trade, I love the way Bitcoin doesn't discriminate like governments do
. Protection against inflation, it's always good to diversify and Bitcoin should be no different, even the most cautious investor should try having 1% of their wealth in this currency just to see how it goes
