On the LBTC text I’d say -0.5% if you trade on Bisq. Maybe you’ll get banned from LBTC I don’t know their rules. Or using the chat, but again if I were your peer it would feel strange if someone who I haven’t trade with tries to use a different method and maybe I would call for moderation.
Something like “ask for better conditions”, giving them the option to ask you for alternatives is a better approach.
Maybe it would be enough to post somewhere different than LBTC that you are offering X price on Bisq, like local facebook forums, telegram groups and some other places you already have some reputation.
Bisq also tries to announce strange trading peers on social media so the voice of, let’s say a Venezuelan Bolivar’s offer, is expanded. Once you post the offer, say something and probably they will announce the offer on twitter.
