hmm no you're not blind perhaps you have to make an adsense or have the account for a certain amount of time. I can't confirm that because I had my account for a year or two before I really began uploading videos so I had the option very soon. When its available you should get a notification on the top of your page that will say you are able to monetize videos just like you will get one that says your account will be able to upload videos longer then 15min.Lol I don't have such thing Am I blind or something ?
Listen to this man. Yes it is bad to monetize gaming videos until being partnered and it is something I should have mentioned but you can monetize a video and then un-monetize it and you will still have the thumbnails.Isnt it meant to be best not to monetise gaming content until youre partnered through a network who has permissions etc?
