Whilst I don't have any money in BetButler, I'm conscious of the fact that I'd mentioned I'd placed bets with them previously in my blog. That means anyone reading this could've followed in my footsteps and got stuck in there.
I'm going to continue doing things the way I have been, but anyone following must know that you do this at your own risk. I've written a piece on Bookmaker Complaints which might help if you're having trouble with anyone. But the golden rule of matched betting (or rule number 1 on our list) is that you don't bet with money you can't afford lose, regardless of how safe that bet should be.
