Bug at mediation payout

[HenrikJannsen]

The change of the min. deposit amount was not applied to the payout suggestion in the mediator payout screen.

Reported by mediator:
I have a mediation case in Bisq where the payout proposal ended up being calculated wrong in the application
Trade amount was 0.0004 BTC
Deposits were 0.0003 BTC
Trade was proposed to be cancelled
The application calculated the incorrect amounts

To incentivize the losing party at mediation to accept mediation rather than abandon the trade or take the trade to mediation they are currently always left with whatever is the greater amount from the following:

5% of the trade amount, OR
0.0005 BTC

Due to Bisq reducing the deposit amount to 0.0003 BTC in v1.9.19 this creates the situation where the mediation proposal made can leave a losing party with a payout proposal of 0.0005 BTC (which is more than their deposit).

As a result the mediation proposal mechanism should be changed so that a trader is always left with whatever is the greater amount from the following:

5% of the trade amount, OR
0.00015 BTC

Thinking more about it the min amount should be reduced to 0.0001 BTC, so at least a scammer stands to lose two thirds of their deposit.

Shouldn't that be covered by using the penalty option? The "seller/buyer gets trade amount" option is for a settlement without loss to anyone. No?

#7408 use the same logic as it is now (50% deposit as the min. amount to payout to leave some incentives to accept the result).

Yes, happy for it to be left as:

5% of the trade amount, OR
0.00015 BTC

I think my suggestion for a lower amount was geared towards a few chargeback scammers we had recently were it would be nice to recommend less than this. But with reflection the previous logic has worked well so if it is not broke no need to fix it.
