If I may ask, what is the advantage of using credit card bitcoins?Can it benefit us? Or just make us incur losses,With unstable bitcoin prices, seems to be making us a incur losses ,!
There is no advantage as such.It is more reliable to just your card instead of logging into your wallet every time you have to make a payment "onsite".
For your regular transactions online ,card won't help much but incase you live in a city where bitcoins are accepted in stores and all you can always carry a card with you.
About the prices ,nothing much to say since the prices remains te same regardless.Also some cards do come with service fees which can potentially increase your purchase.
