Yeah i totally see your point and i think it would have been a very nice move to increase demand and price of ppt organically without breaking a sweat, buying XAUp only with ppt will means all investors who hodls ppt can easily pick up some XAUp Gold Poken and other's who are interested can buy ppt to purchase XAUp.
I think you havent understood it properly. ETH was sold by "Different" ICO teams.. But here PPT will be with their own team. Why will they dump it.? Rather than that PPT team can use these tokens to do more aggressive marketing. As the price would have been high after this, the value they will get will be more.
