Doog,
I thought about what we discussed on the trollbox and you were absolutely correct. I was totally wrong in my calculations and I admit I was not thinking clearly. I greatly appreciate the patience you had with me.
This is the bet that started the discussion:
https://just-dice.com/roll/184417807A winning bet at 98.99% odds, he took home ~0.01134 when the true odds are ~1.14618. The 99% difference was used to pay the "1% house edge". Of course if he had lost, he would have lost it all.
I questioned the bet after seeing the risk to reward ratio, perceived it as an unfair situation, and incorrectly thought that the math was wrong. Instead, I was wrong. It absolutely is a 1% house edge bet according to definition.
It's a sucker bet, you say. I'll go out on a limb and say that if the terms of the bet are "if you win, I tax ~99% of your true odds winnings; if you lose, you lose it all", "sucker bet" is an understatement. I find it unlikely that a player would realize this less-than-ideal situation when they see "1% house edge" advertised.
I think the better question would be "is it misleading to offer this type of bet?".
Any thoughts are welcome.
It's pretty simple.
It takes 1% of the total bet returned, not just the winnings. If the site had a bet that paid your normal bet back 99% of the time, the casino on average will make 1 btc on every 100 btc bet placed on it. I simply suggest to make more risky bets to have fun as there's no way to reliably make a profit gambling on any odds. Taxing 1% on winnings in a 98% odds results in a dangerously low house edge of 99.98% which isn't feasible.
