For people who are interested in how the 100% fiat settlement is calculated, here's a worked example:
Deposit 10 BTC on Sep 29th, considered $1430 deposited
Withdraw 1 BTC on Oct 2nd, considered $127 withdrawn
Deposit 1 BTC on Oct 16th, considered $154 deposited
Added together: 1430-127+154=$1457
The $1457 figure would be your re-denominated balance if you choose to accept, which is ~100% of the fiat value. Payment would be made in BTC using the latest MtGox ask.
TradeFortress offered me the rate of $750 (price was $620 at the time) for the fiat settlement. I offered latest MtGox ask, didn't recieve any response yet.
Did anyone of you used the settlement option after the price fallen from $750? What was your BTC/USD rate?
