the old payment process needs removed and the site fitted to accept btc i don't even know if it's possible
basically this is how the site works
It's a "Payment Randomizer" user signs up by making 2 1 time payments 1 to the admin and 1 to a random user in the pool (the member base) that gets your membership into the pool and admin receives payment and a random user gets a payment the site uses a MySQL database to randomly select which user gets the random payment once you are a member you have various options to increase your chances of getting that random payment by purchasing additional weight more weight equals better chances at random payments.
so in order to get the site to accept bitcoin the whole process has to be rewritten
