What about groestl? Much less power consumption for a much higher hash rate. Myriad shows some promise; plus Diamond (DMD) who could be considered an "old school" coin (therefore ruling them out from being a  "pump and dump", since the the development team has far fewer DMD than early adopters)  point just switched to groestl algo, with a 50% proof of stake kicking in a few years down the line.

It's an interesting move, to be certain.
