WOW, MINTPAL, what a stupid choice, you will get nothing more than dumpers! GRS will be dead like HIRO.
Based on this coin's compelling algo which works well on multiple platforms it has a bright future. Any short-term dumping on Mintpal will only test the resilience of this mining community, which is strong enough to ride through.
Good performance on many platforms combined with lowered ASIC advantage is the ultimate goal of a PoW algo. Grøstl does it better than any other algo in crypto mining today.
What the hell?
We stayed loyal and continued mining even without a dev for two weeks!
p.s. HIC! is the sound Godzilla makes when he chokes on a plane

As one of the most efficient GPU coins, GRS will do very well with Scrypt miners. I mined it for 24 hours to test it against x11 and the efficiency, lower fan noise and lower heat generation was excellent.
Come the summer, this will be a great choice for many miners.
Just my view.
I don't mine GRS at the moment, only because I mine DRK. I still hold GRS.
