There can’t be many of the 2FA titan coins left, at this point.  But for sure, a notice about not buying them would be helpful.
Regarding a class action, that might be an option with payment contingent on recovery. There might not be anything to recover, though. A PI might be able to determine that.
It’s an unfortunate situation all around. I still do like the idea of a physical coin that you can exchange intact, or sweep the bitcoin out of. There are some low denomination tokens currently on eBay made to a pirate theme. Very high premium through. Of course that’s what I said about the satori chips when they were selling for 50 dollars. Now sold for 250. Sure wished I collected a few.
