Devs are quite busy with DAO implementation and I am not sure that we want to spend dev resources on these things too much.
I don’t think I understand what is the real problem here. You can set whatever price for your offer that you want. Simply place an offer at the market price of the Coinmarketcap if you wish.
If the trading fee is the problem, because it depends on the distance from market price. You should only have that problem for the first trade before the price is adjusted, since Bisq will set the price of the last trade as it’s market price. If that first fee is the problem, just make a minimum trade amount so you get the smallest fee possible and then you can take your own trade with a different Bisq account.
