Do you have a certain strategy or is it just your gut feeling? Do you secure your bet on one site by setting a further bet on an other betting site?
I always play parlay on sports betting and very rarely did I commit a single bet, actually, if you have enough capital to bet, I'd suggest you to play single bets with odds of less than 2 but pairs of big bets and you should be able to control your emotions, so that you can profit with ease. if I have enough capital to bet I would definitely do this, unfortunately I never have enough capital so that I always play parlay.
