Do you remember how BTC spiked around the time of cutting the reward in half? I was just wondering the same after reading that we are getting the reward cut in half as well in a few days.
So, that means fewer coins to mine. You will have to buy.
The next few weeks will be interesting. Will the QRK network's Hashrate continue going down or will it stabilize due to a price rise? A few factors...

Honestly I don't remember and the graphs i checked don't remember it either.

Either way , qrk reward has been cut in half 3 times in the past months and ... nothing.
