Alex,
We've always had BitCoins as a payment option because the site is pretty much an exact duplicate of our GPU Rigs website so we had our developer include everything so that when we were ready to let everyone know about the site, it was 100% ready to go, ranked in Google and the other search engines so that we can grow our business quickly, efficiently and ship product out to customers quickly and efficiently.
That being said I believe that we're currently trying to get ahold of the developer of the site to get those buttons removed in the interim.
In respect of Paypal, we wont be using them, whilst they do offer some protection on the consumer side of things, as a merchant, they offer none, zero, zilch, zip.
We may as well just ask every known scammer in the world to order through Paypal using a stolen credit card or actual Paypal funds and tell them once they have the product 'in hand' to just cancel the transaction... In that instance, we're fucked as a merchant and we close shop due to mass fraud or 'friendly fraud' as the banks call it.
Again, thanks for the opportunity to answer everyone's questions, comments and concerns about our ASIC product line, I must head out now though as I have to head to Sheffield for a few hours.
