There are certainly plenty of angles to speculate on. I'm planning for difficulty to be utterly enormous and I still think this is a winning opportunity. For me and others bullish on BTC long-term, it's less about immediate ROI calculations and more about getting as big a piece of the pie moving forward. But to each his own.
Agreed. Actually, I'm not really even that focused on "getting a big piece of the pie." Of course I'd like to make fast money on my investment - who wouldn't.
But for me this is more about obtaining hardware I can use to mine at the "hobbyist level" for at least a little while without getting completely outgunned by the big guys. Plus it's hard to put a price on fun, and I just plain like mining.
