If there was a website you could go to daily where you would earn anywhere from 1 cent - 10 cents worth of bitcoin just for clicking a button, would you do it?
No strings attached, no deposit required. You go to the website, push a button and 5 cents is deposited into your wallet. Would you go every day and do it, or is it not worth your time?
Like a Paid-to-Click site? With lots of scams nowadays, it will be a tough challenge for you but I think even for a small percentage, there should be someone who will test the waters there. Obviously and technically, you will not send the payment right after it was being credited to their respective account and you will set a minimum tier for them to be able the withdrawal, well to save fees. On that reason alone, one can be tired of achieving the minimum amount to withdraw and soon they will abandon their progress.
Why not just focus on the content instead? Not with the rewards, not with the prize, not with the benefits, but anyone will go to your website if there's a useful and interesting content there. Those small rewards are just a bonus.
