Don't many discounted gift card sellers end up to be doing some kind of fraud with the cards themselves (stolen, hacked, illegally obtained, etc.)? The fact that, from your FAQ:
We currently process payments from Bitcoin only.
just makes me feel even more like you're just accepting non-reversible payments so that a scammed payment cannot be reversed. I would certainly want to be proven wrong though.
You should be posting that over at Scam Accusations.
We are accepting only bitcoin payements at the moment because we support bitcoin, and it is easy to integrate. Contrary, We didn't integrate paypal yet due to the limitations.
