Probably I'm late to the party, but try your best to make a transaction with a signed user @bitmover. That will enable you to also have a elevated account limit[1] on the payment method that you've used, which in turn will allow you to buy more bitcoin per day. However, as others mentioned, there's limits on the amount that you're able to buy, which is directly tied to your payment method - see here[2] for more details.
Thanks RickDeckard
For now I am still just selling. And to get a "signed account" I need to buy from a signed user. I will probably do that in the bear market only

But there is no limit to how much btc I can sell, so no problem for now
My recommendation is that, if possible, do look for an opportunity to have your account signed. This would make your offers standout more in the market (buyers tend to prefer signed accounts, as a sign of trust and for the possibility of having their account signed as well).
Other than that, keep at it! Bisq is great but has a somewhat steep learning curve - please let me know if you need further help with it.
