Gen3 tapeout is the reason for the price increase. If they meet deadlines it will go even higher.
I really don't have a dog in this fight. I haven't owned Asicminer shares since 2.5 btc/share. However, as a guy with bitcoin to spend, I won't be buying at these prices.
The market is very thin and a single buyer can easily cause a run like we are seeing now. My statement was simply to warn the newer investors that these prices are unsustainable without better news and waiting might be the better play.
