I just got around to trying the bisq2 beta. it is in the AUR. bisq2 added a mode that is closer to localbitcoins, where everything relies on trust and reputation and there is no requirement for a security deposit. but the number of offers where the seller has any reputation is very small at the moment and I am afraid to take the offers. this is also the only method that is part of bisq2 and no other methods are working right now. you'd have to buy bitcoin on bisq2 and then go through something else to get monero if you want to start from nothing. bisq2 wants to add back monero support but they pushed it to the very end of their roadmap. a haveno2 could fork bisq2 and make monero a first class citizen.
