Which Social Medium is easy for profits

Hello Community,
Which social medium is profitable considering ease of access , time spent etc …

for instance, youtube is easy for profits. it is NOT that strict as what Instagram or Facebook is considering Instagram or Facebook has stringent rules of engagement.

I see people who started three weeks ago with youtube started seeing some profits, I dont think it is the case with Instagram or facebook.

What do you think ? Feel free to add comments about pinterest , g+ as well…

If you can make videos that engage your audience somehow. Go the YT route. BTW, if you are going to copy the content of others to make cash from adsense or CPA… It is pretty dead imo.

Also you should take a look to:

Youtube is changing their algorithm… They are cutting a lot of the traffic that came from Suggested Content.
