If QuazarCoin dies it looks bad for ALL cryptonote coins, so if it's possible to save it I think it's worth doing. Why has the dev abandoned it? Doesn't make sense!
Firstly the coin is not going to die. Secondly who said what the developer abandoned it?
From the start the dev was hardly ever around. but lets back track a little. The dev of this coin tried to relaunch Monero shortly after it was already launched, adjusting just a few things.

The devs response to this you ask? I was simply trolling. Now a good portion of his post talks about haters and trolls that need to leave, go figure.
