The “unused BTC” seems to suggest MyBookie to me - that and the fact they love playing the game with players who seem to have a clue.
Bovada plays games with bonuses we know.
YouWager is definitely not a A+ book in BMR guide.
By any chance was this involving props ? Could definitely see MyBookie being spooked by a winning prop wager/parlays involving them.
Not that it is right at all - it’s just their ultra conservative standards and fact they want rec losers only and go all out in keeping out long term winners.
i am going to say it was heritage cause things have changed with heritage and their sister wagerweb. new site layouts, new mobile layouts, new look for wagerweb, etc.
Yea - could easily see Gabe/Heritage doing something like this - but the fact they paid so quickly makes me think not them. For a once top tier book - they have gotten a reputation as a B-/C+ with their customer service of late/
