Well, at the risk of being called a troll (anyone who has anything remotely negative to say about GAW seems to be called as such) I'm going to post this anyways.
I recently purchased a handful of genesis hashlets, and during the process wondered "what's stopping GAW from removing any of the pools? Or what happens if a pool like waffle pool disappears? How will they deal with those hashlets which are guaranteed a rate off said pool?". Well lo and behold not 48 hours after my purchase they've removed the only profitable SHA256 pool rate from the genesis. My estimated ROI date, which was part of my purchasing decision has now nearly doubled. I only have myself to blame though. Really.
