Your Balance will be locked while bonus is active. You can cancel bonus at any time.
Bonus must be wagered 55x to became a part of your balance.
According to your terms, the bonus was
not part of his balance, so the 5 BTC win was solely generated by his 2 BTC deposit.
55x wagering requirement of 2 BTC bonus = 110 BTC to wager. Minus 23% (25 BTC) already wagered = 85 BTC left to wager to get the 2 BTC bonus
1% house edge of 85 BTC to wager = 0.85 BTC loss.
So if you restore his account balance of 9 BTC (2 BTC deposit + 5 BTC win + 2 BTC bonus) and he will wager the required 85 BTC to get the bonus, he will statistically lose 0.85 BTC and his account will be statistically
8.15 BTC instead of the only
2 BTC deposit you gave him!
Nope, I do not think that they really need to pay him 7 btc, because he started with 2 btc, no matter they win or lose the only way to get this fair is to give him back what balance he start deposit. This is like he resetting their amount back to the start, so everything will be no affect on it anymore, this is seems fairly to him. I think duckdice red tagged should clear right now
It does not play any role what he had at the start or what he did 1 year ago! Relevant is only the point when they misleaded him to click the |Cancel Bonus| button.
At this point his balance was worth 7 BTC + 1.15 BTC bonus after wagering the remaining 85 BTC to clear the 2 BTC bonus =
8.15 BTC.
No one would cancel his whole account balance!
1) If he do no want his account balance, he would simply leave
2) If he continues to play, nothing worse than his account balance = zero can happen
Now tell me what is the reason to cancel your whole account balance instead of proceeding with 1) or 2)?
He did not complete the wagering requirement, we can't simply say statistically while involve in gambling. He may win or lose the entire balance before completing the requirement.
Most casino did this, player could end up cancelling the entire balance after part of wagering requirement has been done, except most of them are clearly written in the terms and conditions that Real Money will be use first before the bonus balance is used. They make it clear, but Duckdice didn't. Duckdice use the same algorithm, thus they should actually write in this way (Main account funds will be used before any bonus funds, an example took from FortuneJack), real balance will be locked while bonus is active is the only reason that misleading the players.
Duckdice didn't make it clear in the terms and conditions, that was their fault, BUT, when cancelling a bonus, there will be a popup box showing up how much balance will be left in your account after cancelling your bonus, if player read before clicking any Cancel | Button, they should know! Even if they are clicking too fast, there will be a second windows to ask for the confirmation, player should read! This was the player fault. Again, player should READ CLEARLY before performing these kind of action, just taking a few minutes to read, easy task, it is the player responsibility. You cannot simply ask for a refund just because of your own mistake. In this case, cancelling the bonus without reading clearly was the player fault, and Duckdice still refund his deposit of 2BTC, fair enough.
