Personally, I have never placed any bets on BetPanda platform but surely I agree that $1 is quite high as minimum for players ...
Which game are you talking about with a $1 minimum? I've tried their slots, and I can bet less than $1 per roll. If that doesn't convince you, check out the slot multiplier contest posted by LM on
https://bitcointalk.org/index.php?topic=5529460.msg65039207#msg65039207. The minimum bet there is just 0.20 euros!
I'm talking about Sports betting on that one since he quoted my post about the 1$ minimum requirement on sports bets which is for me (and maybe for him), too high especially for us casual or small gamblers. As for the slots, $0.20 is I think a reasonable minimum bet, but as somebody that focuses more on sports betting, I find $1 too high although I'm not saying that the Betpanda must make some adjustments with regards to that one.
I think they're just following the standard since most sportsbooks here have a $1 minimum bet. It makes sense because we can place many more bets on slots compared to sports betting. In slots, you might hit 1,000 or more rolls a day, something you wouldn't want to do in sports betting.
