Do you think QRK will skyrocket again? I mean, it only goes down, and down, and down. My impression is that this coin is dying. And it's sad, because I was almost all in with QRK. From my 6 BTC right now I only can recover about 2.

QRK was for me #3 after Bitcoin and Litecoin, unfortunately, people doesn't seem to care much about innoative new coins, most of them just want "new" coins or "fun" coins like Doge..
Look @ Memorycoin.. Almost same story, even though its a highly innoative coin..
I also see it on my pool
