It looks like difficulty has doubled in the past month.
that isn't because of the blockchain though? right? that's just because of the volume of miners?
Will difficulty balance out? or will graphics card mining die in a couple months?
(based on current growth, I'm expecting a 100MH/s build to make less than $50 a month by the end of the year.)
When graphic card mining dies, are people moving to another currency? or are people parting out their rigs and moving on?
What's everyone's exit strategy?
