I think he may be referring to the fact that we currently only accept BitCoin. Once upon a time, we used to accept PayPal, however due to a PayPal policy change that prohibits accounts for being used in any way that is in any way related to distributing adult content, we can no longer accept this option.
As the page mentions, we are trying to find (and hopefully roll out) other alternative options, however this is all we have for the moment. BitCoin is a rather unique breed of currency, which isn't necessarily for everyone. If you want to know more about this strange currency, I would suggest checking out this link:http://howtobuybitcoins.info
