i do not bet much anymore (no mma, some NFL maybe a little NBA come playoffs) and i honestly do not remember exact amounts but:
my biggest win was couture toney, i bet everything in my accounts (5dimes, betus) on couture but he was a heavy favorite
my biggest loss was fedor. he was also a favorite so for about a month any bet i was making i parlayed with fedor. the NCAA teams were winning so by the time of the fedor fight i had a ton of parlays with all wins and fedor pending.
i thought about hendging it and betting the other guy straight up for a smaller amount and locking in some profit but i thought he had it...he lost
