For what I know is, the profitable traders are all never share out their trading strategy out to public.. It was like a special secret recipe for a restaurant. And yet, if they got such free time to create a video or blog to promote their strategy why not they put more effort into trading as the profit earn much faster than the follow can be created through the promoting.
Profitable traders won't want to openly share their 'winning trading recipes' for free on YouTube only to generate revenues from YouTube ads monetization. Also I notice that 99% of traders who teach are not able to show performance proof of say 2 years. Doesn't make sense at all! What do you think?
There are many forums on the internet that are useful. Advertisements are everywhere, you cannot really avoid them - especially on blogs and YouTube videos - but there are many forums out there with strict moderation and/or a separate subforum for advertisements and referral links (including this site) where there are genuine people and good discussions.
