To the guys worried about ROI on their hardware:
Alot of the doom and gloom is strictly predicated on the current BTC/USD exchange rate.
Bitcoin has come a looong way from $0.05 usd / btc to ~$125 usd / btc, so hang on to those bitcoins, an re-examine your mining investment in a year or too. I believe you will be satisfied !
That said, it is probably true that it is more lucrative just now to buy btc and hold than to mine.
I'm mining because I wanted to learn about BTC from "the trenches" so to speak, and don't regret it one bit.
Love the BitMinter !
