I highly doubt the devs are buying back their coin. If they were a real company that issued a form of real shares, they would be in for a shitstorm of litigation after opening business back up and pretending to shareholders that nothing happened. If the devs just pulled a scam(which seems the obvious answer) they would just move on to making a new coin. No need to buy back for pennies on the dollar when you can just cast your net all over again for free.
