I think you are getting it all wrong from the beginning as regards the term used. Judging by what you narrated, you are referring to Bitcointaker and not Bitcoiner. Bitcoiners are those who are engaging in Bitcoin, and even if you are engaging in Bitcoin but still silent about it in this context, but instead refer to the forum itself as your source of income, then you are a Bitcointaker in my opinion.

Regardless, let anyone think whatever they want to think about you, so far you are earning through legitimate means, continue to do you and let your conscience do the rest. I expect anyone earning here (even if that's their only source of income) to be proud of it as they are Markerters. The last time I checked, marketing job is a very good job no matter how little you earn from it.

Anyone who is not satisfied with it should find you a better job or keep shut. Case closed!
