An increasing number of retailers (mainly online) are starting to accept bitcoins. But is there any actual research to show accepting bitcoins increases sale of goods. A good example would be a very stable company that makes $10k revenue per month accepting bitcoins and the next month they make $14k. This would show accepting bitcoins increased sales by 40%.

As a bonus, the research could also show if there is a bigger increase in sales for online retailers compared to physical retailers accepting bitcoins. This could encourage more stores to accept bitcoins.
