Execoin's hashrate is low today because it's working exactly as designed.  People who want to mine and dump for Bitcoin are mining something else.  Execoin's value is that in the future, when GPU mining becomes unprofitable, it will be in a great position to attract the miners who would rather not sell off their rigs.  Today, it's just another altcoin that requires a bit of extra futzing with your rig in order to mine.   It doesn't make sense to worry about the cake being frozen when the party is still weeks away.

I understand that if you've been mining or investing in Execoin you'd like to see its value go back up.  I do believe Execoin stands a great chance of being one of the bigger altcoins after the powerful Scrypt ASICs start shipping.  Until then, the best thing to do is keep mining, holding and buying if you believe in this coin.  Forking Execoin seems the surest possible way to kill it.

At the very least, I'd recommend the developer sit back and watch what happens to Dogecoin in the coming days after their reward halving.  It could provide some great insight into what may happen to Execoin.
