good point , actually would love to see sportsbet showing their max bet as the majority of other fiat sites do
this way whales won't end up depositing and find out that they can't bet their whole deposit , this would be disappointing for some
also I'm afraid that in some cases if someone deposited and couldn't wager the full amount then sportsbet may consider the withdrawal as a try to mix the btc , this has happened with cloudbet sometimes where people couldn't bet their original deposit and then the site didn't allow withdrawal cause the players made no bets
still it's better if sportsbet can just show what is the max stake for each selection
I do believe there is a specif strategy that Sportsbooks use for not making this type of information readily available.
That said, I also agree w/ you that sites should disclose the maximum amount they will accept on a given wager.
This would, as you mentioned, alleviate much confusion.
Many bookies on here are vague; giving answers such as "before kick-off" or "within a few hours before the match" when questioned when the maximum wager will be raised.
I'm sure many people have deposited into Sportsbooks before, made their max wager, and then had to withdrawal the remaining balance that they wish they could have bet.
All the while, the Sportsbook has to pay that extra withdrawal fee that they wouldn't have had to if the maximum wager had been disclosed from the get-go.
