Instead of doing the pay to get rid of ads model, why not follow a more successful business model like freemium. I for one can simply just delete the div that holds the ads, and since i leave the tab open i only need to do this once. Where as, i WOULD pay for a premium membership if there was extra features, such as more chart analysis tools for example: Bollinger bands, Ribbon MAs, etc.
Thank you for advice. remove div or pay premium base on user's charactor, If the user dislike privacy or not. I have a lot of technology to detect the ad has been removed or not such as check canvas width, but I wouldn't do that. everything is base on consciously.
The premium features are still under developing, it would not be take long time.
