I just invested in 30 290x mining farm and just got them up and running couple of weeks ago. I now feel that it's too late and that I should have known and invested in Gridseed instead. Now I'm wondering if should take the loss by selling by GPU rigs now to convert to ASIC farm, gridseed in particular, but the one major speculation I'm hoping for is that GPU mining will continue to be profitable because of nscrypt. Then again maybe nscrypt will eventually work on these asics...
GPUs will always be useful because coin creators will just adopt different algos for which there are no ASICs yet.
That is simply an opinion.
