Doesn't betsofbitco.in take out 10% from the losing side though? For a relatively even-sided bet like this one that would be 4-5 times as much. And betsofbitco.in took like 5 days after the resolution date to pay off a winning bet I had with them which I was not amused about.
Bitbet has some room for improvement, but I still prefer them.
+1 no registration required at bitbet too.. I like that.
Plus all my winners have been with bitbet and all my losers with betsofbitcoin.in.
