1) People are not really buying stuff with their bitcoin
2) The future of the bitcoin as real currency is gloom.
Please prove me wrong (as a person who hold a few coins....)
According to Quantcast statistics Bitcoin users are
* 88% male
* 48% have annual income above $50k
* 35% have annual income over $100k
* 26% have annual income over $150k
It's no surprise that Bitcoin users also tend to be a bit more techy. You might give some thought about your company's clients, do they fit well into the typical Bitcoin user? Bitcoin will grow into different demographics but these are the current statistics.
As others mentioned also think about marketing and promotion. The people using Bitcoin are generally big advocates for the currency. Think about promoting a special, deal, or service just for them. They will likely create raving fans, tell their friends, and talk about your company on forums like this. Create a simple press release about your company accepting Bitcoin (and make it obvious on the home page of your website) and then share the press release with Bitcoin blogs and advocates. Just a couple of ideas, hang in there and good luck!
