I don't use Robotsats but I do use Bisq. When it works it's great but be careful, their support is seriously lacking. If you get an issue or a problem then it's hard to get answers or help, and in a dispute you can expect a kangaroo court system run by aloof dismissive people who don't answer questions and believe their system is infallible.

Open source software, great: but zero organisational transparency.

And if they think their system is that good that they can just leave it running basically unattended while they collect fees, then they'll have a rude awakening at some point. I imagine somebody will end up taking legal action over major losses caused by an amateur quasi-legal decision made on the fly without any discernible rule-set.

I'll still use it, I just think if you're moving large amounts at a time then try something else. Realistically they're going to have to open the door going forwards or they'll get into trouble.

Bisq is great, I guess many don't try it because it's a bit more complicated to set up. Liquidity is def better in EU
