Referrals, referrals, referrals !!

I enter youtube, and I will look for information, learn more and have knowledge about bitcoin and what is happening with it in Brazil and in the World (I know youtube is not the best source 

of information, but I like the opinion of the few youtubers who treats Of the subject on youtube).

But what I see is many, but many, videos about Bitcoin, but with the sole purpose of: Winning and Gaining more referrals. Unfortunately a lot of these videos shows sites like Gladiacoin, 

Genesis (True Ponzi schemes) and other sites of the same style. There is video of a woman fighting because people registered on her site did not invest. It sounds like a joke !!

Anyway, the essence of what is happening with Bitcoin is rare. Few channels bring this theme into their contents.
