I mean, we can see that this idea that the stock is too risky to quote is not true because there is a two-sided market in it right now, which can be traded on multiple platforms. The only actually existing peculiarity here is that Robinhood is not allowing customers in possession of 100% margin to open a new long position.

On exchanges. Those are buyers and sellers as well as market makers. Robinhood connects to a subset of the latter.

Nope, pretty much just market makers.

Hopefully others realize that downvotes on HN do not change the reality of how market makers function.
