The key in my experience is to keep transactions small and uninteresting. Don't do $50,000 a month in one transaction. Break it up into $100.24 to $527.43 type transactions daily across 5 or 6 bank accounts.
Not a bad idea. Well, I have have any problems cashing out my bitcoins to fiat yet I am a bit worried. I don't have any bank accounts yet where I can transfer my earnings I do this through remittance centers.
But incase I open up a account in the future I would keep this in mind.
Also the once in a month thing is white a good technique.
I hope those things you've heard are not true incase.
