Probably been discussed before but I'm not in the mood to search for it.. I don't know how the Difficulty is being determined, but the upcoming increase of 23% is really feeling like being ass raped. I have a real problem with Difficulty going up every god damn 12+ days.. At the rate it keeps increasing, the only people that will make any money in mining are those that had $100K+ to invest in mining gear or cloud mining and was able to get around 15+ THS.
I thought having 1.3 THS was kickass, but it ain't shit... I would have been making over $100 a day 5 months ago.. Now I barely make $25 a day. What the shit is that?!? Unless BTC suddenly goes to $2000+, mining isn't going to be worth the $$$ anymore..
