Question: Can you have so much love for your team to behave like this guy that even when you know your love fans team would loose a match, would you still further stake on the match against your team?
Remember that we are catching funs here and whoever chasing after profits is at its own will.
The initial goal of gambling is to win. The purpose of fanatism (I hope I made myself clear) is to root for and support your team. It is necessary to separate gambling from fanatism, because in this case the goals begin to contradict each other. Otherwise, this leads to such stupidity as an obviously losing bet. Mixing the cold common sense of a gambler with the hot emotional expectations of a fan will certainly end in losses.
I would not make a bet that was unprofitable (in my opinion), but as a compromise I would simply ignore the match of my favorite team as a subject of bets. That is, I would separate gambling from fanatism, because I would devote time to these entertainments at different times.
