At the moment, you spend $1 to play. If you "win" $1, you actually break even. A winning bet should return your initial stake as well as your winnings.
Increased to minimum $2 in 1.5.0
Part of the risk of gambling is you may lose that buck. Getting it back is better than losing it. I don't completely disagree with this suggestion but it makes sense to me
I'm only suggesting it because that's how gambling works. Nobody would ever gamble if losing cost them their stake, and winning would only return it. Where's the incentive? :)
