What ways could I develop this in to a bitcoin PTC/GPT site
http://paid-tasks.comI have implemented a wheel of fortune and also a lottery ticket system but I would like your suggestions on how I can improve it to become more of a bitcoin environment.
If I were you I would invest changing the design of your website, it looks so old.
Maybe you can check where are your users coming from and if you have lots of non-US then you may include another languages.
