Two of us at CryptoBets use the DEx constantly. I create tokens, one of my partners sells them at market price. See bottom of this post for more about that.
The hardest part is letting go of what you wish the DEx would be, and accepting what it is. The escrowing feature is what drew us to it.
Does anyone use the betting menu? We looked around quite a bit for anyone who was using this, and it seems like the only people who were acting as oracles last year have disappeared this year. We were never able to match a bet last year, either.
