If I wanted to use bitcoin in my everyday life, I'd much rather go for a debit card than a credit; overspending is bad for you anyways.
And with the information provided I have done what I needed to know and not put one more thought into this obvious ponzi scam site. Offering double your amount back is a sure tale sign they are not substantial in their proposed business model.
Doesn't even say which credit card house they are getting these cards from.
So they are just phishing for fools in a barrel to join them and send some satoshi their way.
Nice script site cloaked in pretty graphics and presentation as Neuroticfish pointed out.
Stay away.
Locking thread.
Thanks to all who gave some proper advice on this, expect for the oh too good for anybody else response towards a valid question about a "new site" to the fold of the ponzi scheme game.
