We will not upgrade hashrate if we think we will not be able to deliver. A hashrate commitment is a hashrate commitment, whether that is for 1H/s or (after upgrade) 6H/s. Mining will start at Zcash launch, and you will have the hashrate we promised, but due to the experimental nature of Zcash there simply is no guarantee nothing can go wrong.

In addition, we have good news coming very shortly!
