It was clearly a scam right from the very beginning. I do not know why some of the people in this forum did not think it was, maybe they thought they could make money with it.
At the end, the fact was releasing it. This one turn into the scam coin.
When zcash was about to be released suddenly 2 Asians released a white paper for zcoin.
It was repeating in many times. Seems like the hurry behavior.
The zcoin website was made to look like they invented the zero coin protocol with all the testimonials posted by known developers of bitcoin.
The lure purpose?
