So, the question is... Which are you better at: selecting the right bet or managing your bankroll?
All, if you're experienced in gambling and also gamble responsibly then there's no need for you to worry about because you always know what's best or good for you, managing your bankroll is another thing one does not need to be taught how to do so except we are not upto task in what we do while gambling.
And, how has it been going so far? Are you profitable or not, and why?
You can ask a question like the reporters, everyone will have something to say concerning this, gambling is not for making profits, but when you are good at what you do and you're satisfied with the pleasure in it, that becomes a profitable thing to you and not until you win or loose.
