@Limkpin I'm sorry you feel that way.
We're a small team and can't spend our time on a feature that we know a very, very small group of customers will use. Having already had a 3rd payment option (Dwolla) in the past, it isn't a trivial thing to integrate a new system that we must maintain. It means changing much of our checkout system and fraud tools (plus the ongoing maintenance and testing), with very little return.
If Bitcoin were a growing, transactional platform, we would do it. However that isn't the case.
Because of Bitcoin's lack of transaction volume and the ongoing development cost we would incur to support it, it doesn't make sense. Just giving the honest truth...
