PTS still alive = more confusion and less people focused on a single product. That's not good for marketing.
I don't really care about PTS being kept alive, AlphaBar can do what he wants to, but by doing so it's obvious to me that he goes against the interests of BTS holders. PTS has nothing of value to offer now : 1) it doesn't represent the founders anymore (since so many people sold them), and 2) it has no useful functionality. If I am wrong on these 2 points, I'd be happy to reconsider. But if PTS don't represent people that helped build the ecosystem anymore, then they don't mean anything, and should be worthless.
In my point of view, the only reason alphaBar tries to keep PTS alive is an investment bet : he wants to earn some more money with his PTS and the one he probably bought at low price - money that, in my point of view, he doesn't deserve, as the BTS allocation already made PTS holders whole. I cannot see how maintaining a useless coin can generate any value for the community.
And I haven't even sold my PTS, assuming they would have no value after november 5th. I'll be happy to sell them if the price comes back up.
