Actually, I didn't make my bet yesterday in the evening, on your site, because it was down to 1.34. 10 minutes ago, it was 1.44. Now again, it is 1.37 again,

What algorithm do you use do calculate odds? Btw, your site is not clear about when is the deadline to place my bet. I though it was today, 6 AM, but it seems it is still open.
Someone recommended BetMoose, yesterday evening I was unable to find this:
https://www.betmoose.com/bet/grexit-greek-bailout-referendum-2015-1202Now it's there again; confusing.
OK, we still have time 'til the evening, which site gives me the best odds if I want to bet on the YES on today's Greek referendum? I only want to bet - as for today - on the referendum, no Grexit, and such.
