All users must have a valid Bitcoin wallet with a minimum of .0001 BTC in it to register. - This is done to give the advertisers a high quality visitor. Someone who has a wallet and has at least done one transaction.
I don't see how that does much to ensure visitors are "high quality"...
If anyone has any tips on marketing this site, or would like to help me I would love to send some donations your way.
My tip would be to remove that odd requirement which makes your site seem unnecessarily suspicious, especially to noobs who may not fully understand how Bitcoin transactions work.
