What if an offer is not accepted for some times and no trade occurs.
How does the vendor gets his security deposit back ?
To create an offer, you only pay the trading fee. No funds leave the original address until the offer it’s taken, they are just not spendable for Bisq wallet.
Once you cancel the offer, you can spend this reserved funds for the security deposit.
Just a reminder, instead of removing the offer and paying the trading fee for nothing, you can edit it at Portfolio - open offers and use another payment method or make it more attractive for the takers by reducing the spread.
