I guess there are just people out there that want to take the safest option as much as possible? I mean I guess that would make them have low a f profit, but well, some people have the mindset of "profit is profit, no matter how small". Especially if you consider how gambling itself can pretty much make your entire bankroll disappear. It probably isn't a matter of even if it's worth it or not cause as you can see it isn't, but it is safe. I guess that's the price they have to pay to be on the safe side.
I bet normally on the teams I like though, regardless of the odds.
If that's the case then it's more make sense if those bettors with that mindset will make a parlay set with 1.02 or around odds.
If my Mathematics is correct, in 25 parlay leg bets with all odds of 1.02, the estimated profit is; $10 bet = $6, $100 bet = $60, and so on. But even at 1.02 odds, there is still a chance of losing and it turned out it's riskier to bet on 1.02 in a parlay.
I don't want a problem in my head, just ignore odds around 1.02, simple as that.
