Yes, it’s been awhile since I’ve posted. =) The GPU mining craze all but died three years ago with the rise of ASIC hardware for scrypt (litecoin) miners. But if the last few weeks are any indication, it looks like we may be in for a major resurgence in popularity.
Bitcoin is currently trading at over $1200—a roughly 400% increase in the past year. Equally interesting is the performance of a couple alternative cryptocurrencies. Ethereum is at ~$32 (up 300% in the last year), with a market cap of $3 billion—about 15% of Bitcoin! Dash is at $100 (+250% over the last year, with much of that gain in the past week).
Dash is based on the X11 algorithm, which means ASIC hardware dominates its mining scene—and getting your hands on an X11-capable ASIC miner is currently fairly difficult, as they’re mostly sold out everywhere. But Ethereum is exclusively minable with modern consumer-grade video cards, and it’s currently quite profitable to do so.
Read on for some “back of the napkin” numbers regarding Ethereum GPU mining profitability, and some current hardware suggestions.
