Personally, I wouldn't, because I don't feel comfortable doing so. If the club I support is playing a match, but I'm pretty confident they can't win, I just don't bet at all, because it doesn't seem right to make profit through the defeat of something I like very much or support. I would feel ashamed if I did so, as it really sounds like someone who is able to do this isn't a supporter at all, but a practical person who changes from side to side accordingly to what looks more benefical to him financially on the present time. I'm not in favour of such mindsets.

Moreover, I guess that is what the ones you support would expect from you: to be together even on the hardest times and during the defeats, isn't it? So that is what I think I should go for.
