Pretty sure that's 99% of what YOU found. That doesn't mean that all bookmakers are scammers. It's just that maybe some are rather unsuitable for what you need or well, you guys just don't meet eye to eye, simple as that. I've mostly tried stake and nitrogensports, though seeing as you already name-dropped them I'm guessing they didn't suit the stuff that you need.  It might be better OP to list out some of the bookmakers you've tried so that others can easily filter out what you've tried and what they've tried. That, or well, just list out some specific ones you want.
