The key point here is that I can use a text editor to edit bitcoin.conf and save there.
It's actually very easy. You can just use Notepad.exe for this. Right-click and 'open with...' Notepad.
I DOWNLOADED notepad.exe from the Microsoft Store. I then navigated to my bitcoin.conf file and right-clicked on it and selected "open with notepad." I then entered my parameters, one per line. When I saved, I see that my file now has changed its name because it's associated with notebad but it's still a .conf file and it's in the same location. I also see from properties that it has ~ 27 bytes (from the new text) whereas before it had none. IS THERE ANYWAY TO DETERMINE if these new config. changes are operational, just in case I made a mistake?
You don't need to open ports if using Tor, since Tor basically tunnels everything. That's one of my favourite aspects about it; no need to set port rules, no need for static IP and of course no risk of open ports in the router's firewall.
This appears as a contradiction. If bisq.network runs Tor by default, why does its documentation specify ports for mainnet, etc. Is it just a FYI that Tor uses these ports and that they do not need to be set manually? Compare this with BTC Core and 8113. If I don't set that port trigger in my router I will not have a Full Node as my "in" will be zero. And since bisq.network uses the BTC blockchain for verification, I think that setting that port is mandatory.
As a side question, do I have to do any configuration for Tor or is the process completely automated? And thanks for your help.
