The 5% rake is pretty high however compared to the other sports betting sites that use BTC.
Mind naming them? OneHash is the only other mutual sports betting site that I'm aware of, and they also rake 5%. If you're talking about traditional sites, no one has a 0.5% to 1% margin.
I'm not offering a bet here but out of curiosity what odds would you offer on The Village Idiot answering this or going back and correcting his false statement?
There's probably a random Ethereum dApp somewhere with a low rake (but probably zero volume). If we exclude those, I'm going to say 33% chance of ignoring, 66% chance of deflecting, 0.9% chance of actually knowing something and 0.1% on going back and correcting.
Let's say odds of 2.8/1.30/25/100 respectively (with some margin of course

)
Not actually offering this
