If I may ask, what is the advantage of using credit card bitcoins?Can it benefit us?
There are many advantage of using bitcoin debit cards specially when doing online shopping. As bitcoin is still not accepted by many merchants around the world, these cards can be used almost anywhere where credit cards are accepted and even in ATMs to quickly spend and use your bitcoins.
Not only bitcoin there are many card providers that accept multiple alts for deposits, which I find really useful and I am using one of those debit card to spend on domain registration, hosting and facebook advertising.
