While I like the idea of this new system, it doesn't earn as much as the previous one. Before I had been able to click 33 ads once every minute, 33*60 = 1980 satoshi/hour

With this system, there is a 6.5 second delay between each add. 60*60/6.5 = 554 satoshi/hour

The only advantage to this system that I can see is that it is automated and would not require you to be making any actions, however, you are making nearly a quarter of what you did with the old system even with the 33 ads. And you can't run this one forever anyways, as you require a captcha that prevents you from being afk either way. Do you think you could implement BOTH systems? So that I can leave it automated for a small time, but still have the option to do manual clicks

Well at this rate, in order to make the same amount as previously, you would need to make a 1.8 second delay. However, as you said, this would complicate things for users, even those with a great CPU.

If you are willing to remove the captchas that need to be solved, then I guess pushing the delay down to 6 seconds would be fine. Even though it's still only 600 satoshis/hour, the fact that it's completely automated would make up for it I think.

Up to you, I'm still gonna keep using it either way
