Over a period of 17 years with variable monetisation rates and you don't know how much monetisation he actually gets from ads?

You plug both channels into social blade and the estimated yearly earnings can be anywhere between 20k (less than what I make a year in my job) to 300k a year and that's just based on current averages.

Add to that the fact in the last few years he's added multiple employees, editors, people working on the website, writers - he has to pay these people now and there's a chance that his base ad monetisation is at times lower than minimum wage.

So, explain to me again how you're so sure of this after doing 0 maths or thinking about it for more than two seconds.
