I came to figure out, why would a consumer/customer use Bitcoins?
You have to pay the 3 cent fee, while you dont have to pay anything when paying with a credit card.
So what is really a benefit for using Bitcoins, customer wise?
many things that cause customers to use bitcoin than other payment system. perhaps because bitcoin shipping costs are cheap and quick transactions so that customers flocking to use bitcoin. we see other payment systems such as western union is very expensive shipping costs, it resulted in customers switching to bitcoin
