More and more merchants are accepting bitcoin. Bitcoin as a way of payment method is increasingly raising the awareness of public. But the problem is that ppl have no incentive to buy and spend bitcoin. Now there need be some kind of trigger to push ppl to adopt it.
It's not that they don't have incentive. The problem is the bottleneck of buying bitcoins. Bitcoin is the best online payment method especially for merchants. Meechants will understand that sooner or later and they 'll start offering discounts for bitcoin purchases.
