The process is fairly simple and the overall experience is good and user-friendly. However, I have one concern: - During the start of the swap, it tells me that I have 120 seconds to submit the offer, and if I don't do it, the maker has the right to keep 2% of the amount. I don't understand why this is needed, it says it is for "anti-spam purposes" but 2% is lot of money. What happens if I simply have a power outage at that critical time?
