I think we are on the same side. I’m just exploring the playground and possibilities which could maybe lead to another idea solving this for both parties.
Actually, Bisq is still in a good position to experiment a bit with such settings. The userbase is comparatively relative small. Experimenting with custom fees as an opt-in option with some clear warnings might be a way to determine how such an option is adopted by the community.
I guess, it is less of a problem than we might think. As users get a clear red warning and need to accept a sentence similar to: “I’m aware of the fact that choosing a too low value can lead to … x y z.” I doubt may users will even think of enabling such an opt-in feature if they don’t know what to do.
Additionally, as long as this option is not touched, Bisq behave exactly the same as is does now. Only by accepting the opt-in option those offers are shown in the offers list at all + clear warning sign, too.
And on top if it, an algorithm checking https://bitcoinfees.earn.com/ API denys users entering lower satioshi classes than 5 blocks eg. Giving users something which makes it impossible to enter an infinite transaction. Those conditions have to be explored, sure. That’s why I’m bringing this up.
Takers who accept such custom marked offers (from the list) know what they are doing. I even doubt many of those offers will be listed or taken. But it might help to explore the playground. Moreover, I’m pretty sure, there is an algorithm which can optimize fees in a similar manner automatically later on. If we don’t try we might never know.
Just my thought of mind. Who knows, this might lead to a brilliant new idea solving the fee issue for all mempool situations to come.
