As of yesterday they changed the rules of the exchange as follows:
Pay no fees when you "sell"* on MANSION Sports Exchange - 0%
Pay only 1% of the win amount when you "buy"**.
No big complaints from me. Obviously I would like everything in life to be free but it had to happen some time. 1% was the best I could have hoped for. Only time will tell if it increases.
My question is regarding calculating the "to win" amount of a bet.
It looked to me yesterday like they were actually showing you the to win with the 1% subtracted while in the confirmation screen (which would be very good IMO). It's a little tricky to tell because Mansion is always rounding things off (due to odds and currency conversions I believe).
I'll pay closer attention today - but I'm just wondering if anyone knows.
