So you mine coins by watching ads and solving captchas?
No, you don't have to watch ads to mine the coins.
Watching ads is the possible way to bring demand for the coin into the Sybil protected network.
And why would you democratize earnings by burning coins from advertisers rather than paying them to consumers of ads?
Unfortunately it might not work. There is no way to prove the ads consumtion without establishing a trust. People may click ads without intention to consume it. Advertizer may also decline to pay for the ads consumption.
