There’s no way to estimate YT membership numbers… we have no idea how many people signed up.see... would it then be an unreasonable estimate that he might earn $2500 or $3000 combined?
But my guess is, excluding the sponsorships, he is getting $7000-$8000 monthly from AdSense. For each sponsorship he can get between $1000 to $2000 and if he has an affiliate link, get a percentage from each sale going through his link.
So he’s getting a healthy paycheque each month. His problem (?) is that he’s clearly spending a lot more on material and labour. But then again, they can clearly afford it… unless Gwen has tightened the purse strings
