I don't know where did you guys get that $1 minimum bet info but be aware on Betpanda, depending on slot providers, you can bet as low as $0.10 on some slots and most common minimum bet is $ 0.20 : I really don't get why all this talk about that $1.
Only reference to $ 1 minimum bet I could find on the site is in term an conditions of "Weekend tournament at Betpanda" in which there is a leaderboard with nice cash prizes awarded for people placing in top twenty positions where only bet placed from Fridays to Mondays counts and minimum bet eligible is $ 1.
But, again, you can easily place $ 0.1 bets disregarding that promotions.
People think that the more spins they will have with $0.1 the more chances they will have to hit a high multiplier, but the truth is 50X on a $1 is better than 400X on $0.1bet in terms of returns. This is just basic Mathematics.
If one feels like the $1 minimum bet is so high, then they should not participate. Simple as that.
For that case (weekend tournament) with $1 min bet, I do agree with you that if $1 is too high so simply do not force ourselves to participate. However, as I've pointed out previously, the case is not for that tournament but for sports betting in general which has $1 min bet. I know there are still a lot of gamblers who do sports bet with bet amount under $1, usually they are trying to place parlay bet with high odds. It is not about which one is better between $1*50 than $0.1*500 or even bigger multiplier, but it is more about user's financial ability or bankroll to place bet. I wont be hypocrite here because I am small gambler as well and I average bet amount is always small, so if there is an option to bet on sports lower than $1, it will be much better both for the players and the casino.
