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?
If you think you have to pay nothing for buying something by a credit card then you are in a great illusion my friend. The bank charges you quite high if you do not pay at time. It will incurr charges on daily basis.
