Mobil App would be nice? Definitely.
Online shop would be nice? Definitely.
Better bitcoin support would be nice? Definitely. But this is not a question (also not related with any payment processor).
Any PayPal guarantee ClixSense will be fine without ads? 8 levels upgrade system will be ok? The Casino related offers will be ok? And don't get me wrong, PayPal for me the best payment option, and also my favourite payment method, and i really want it back (and i know it's very popular), but i just don't think turning ClixSense to a "Tier 1 country only GPT site" would be a good decision. Statistical geography, here we go.
