Tell this to the football fans, almost all of them love doing this, the higher the numbers of pick they have the higher their rewards, this is what all of them think about, nothing else, as if they are certain about winning.
I have only seen a brother who choose one match or two and risk money on it, mind you he always have better results than those greedy gamblers that likes packing up to eight or even ten matches at once, they have this stupid idea of making million in one go.
Almost all football gamblers that I know do this and they never have good ending, not even once, there is always a loss out of all the matches that spoil everything for them, it's not good to be greedy in gambling, definitely not the right place to use greediness.
That's like betting on the national lotto. The chances are way too low, especially in football games where there is a chance that the game will result in a draw. I mean, it's better if there are just two options where at least you will have a 50 percent chance unlike having three options which decreases the percentage of winning. Truly, I have seen a lot of football fans who do long parlays and I think it's a waste of money. Well, there's still another chance for them if they can catch the cash-out option while the next game is not starting yet.
I mean, I've done that before but only in a tennis game. I saw my chance to gain x50 and I didn't even think twice about pressing that cash-out button because for me, that's already a win and I don't need to pursue the next games because I don't really have any idea about it. I just made that long parlay for fun which I think was successful.
Lots of single bets though might have a better chance but like OP said, it diminishes the analyzation focus on the next games as we tend to not care too much about it, unlike the first bet.
