I don't have a need to exchange funds, so that wouldn't make sense. But I haven't seen a reason not to trust them.
You mean that you never sell or buy bitcoin?

Not only on Youtube, it's totally normal on TV, internet and in newspapers too. Only when some scandal hits the media, they suddenly start a boycot to rescue their image use the free publicity. Other than that, it's all about the money.
But newspapers don't need to keep much of an image. I like to think we could be different.
I just gave one example of youtube but I know advertising scheme is the same everywhere, maybe they only target different customers.
Companies in bitcointalk forum are targeting people who use bitcoin, but we never know who can turn into scam or they just shutdown business without explanation.
In recent months first it was betnomi casino and now whirlwind.
