the equihash price on hicehash has just gone into crazy mode 
Thanks for the pro tip. I'll point my hash to there instead.
I've seen pump and dumps on ico's and random alt coins - could this be one for gpu mining!!
If anyone knows of a mining difficulty chart for bitcoin gold (like the one on coinwarz for ethereum and a few other coins) I'd be really interested to take a look over the next couple days. I think I'll wait until the hype settles down to start mining (although if it moons I'm going to be really annoyed with myself!)
