I agree wholly with your first point. Obviously, as someone who’s responsible, one should not bet all the money in his possession on a single bet. You don’t need to bet a shit load of money on a single bet even if you’re convinced it would end up in your favor. But then, what others do with and how they spend their funds isn’t any of my business.

People would have varying opinions on your other points as I personally don’t see anything wrong or weird on betting the same amount on every bet or placing more than a bet a day.
