It can absolutely be part of a disciplined strategy as long as you treat it like any other financial instrument in your betting portfolio. The danger only comes when people ignore their bankroll management and start chasing losses, but that is true for sports betting just as much as it is for any casino game. If you set a goal, determine your win/loss limits, and stick to a predetermined strategy for your bet size, you can definitely have a productive session. It is all about how you frame it and whether you are capable of maintaining the same level of discipline you would use when betting on a cricket or football match.
