It seems like this territory will make the most sense as a sub-territory, once those roll out.
One of the problems is that many stackers have muted pretty much all of the "peripheral" territories. That means many of the best people to answer dumb questions are never going to see them.
I do think the role siggy envisions for ~bitcoin_beginners is really valuable, though. The kinds of content that most people find valuable in ~bitcoin is generally overwhelming for newcomers, while the content that's valuable for newcomers is too simple for ~bitcoin. Crossing those streams benefits neither.
