It isn't that differentiated from everything else, functionally...it's basically marketing. "Because POT" is not a good answer to this question.
Bingo, and without differentiation or widespread acceptance/on the ground use, it's dead. People were relying on the hyped 4/20 launch for acceptance.
As far as the attack goes, I actually commend the devs for working on it so fast. They've been traveling and working their asses off. To the few that are jumping ship because of it, please leave quietly. My god, you'd think the devs were diffusing a bomb or something, hell, you're like the people that freak out in front of the guy who's JOB it is to do that- it's not helping!
What did they work on? The 1 potcoin dev angered someone among the scrypt-hash gods, and they decided to basically pick up the small infant coin and play with it like a ragdoll. The devs did nothing to stop the attack, nor could they, and for all you know it's still going on and you guys are on the wrong chain.
Again, devs have done nothing. Talking about changing the source code isn't fixing the attack, it's trying to run away from the attack and use a different defense mechanism. In the end, if you have a scrypthash god with more than your network hash, you're just an ant beneath a very large finger.
