I’ve added my XMR account in Altcoins but now need to send some. How do I get my XMR account to appear in the list of address to send from?
How did you add that altcoin account with no XMR address? There is no XMR wallet in Bisq, you need to use an external one, and use an address from there to send and receive XMR.
I have an XMR address from Monero GUI. Just thought I could use Bisq as a central place to handle my XMR wallet too. Maybe that’s not possible.
No, there is no Bisq XMR wallet. You have to send or receive the XMR to or from the Monero GUI wallet.
