This stinks of bull shit, sportsbet.io are paying Watford football club literally millions of pounds per year to spoksor their kit. They are a huge company now.
There is no fucking way in hell they are going to risk their reputation & screw you for such a pathetic amount.
Edit - So its your fault for making a bet with money deposited that had 0 confirmations on the blockchain so you were trying a double spend.
You are an idiot & a liar.
I think they blocked my withdraw because my deposit got confirmed after my bet settled.It's mycelium wallet error that it sent tx with 0.01$ fees and it took long to get confirmed.It wasn't intentional.I also say they should have 1 confirmation requirement on deposit and placing bet but they don't.
