Profitability at 29 mh/s eth is now at $0.80 per card, per day, for most countries, I wonder if the profitability will crash to negative this time hehe, soon eth will have a 30 seconds block time, that will probably take profitability to $0.10 per card, per day, soon the greatest GPU depression will start hehe
That's still a ROI of 10 months for cards bought at $250, which is about what can normally be expected. Profitability going forward for the next couple of months is going to depend on if the market can recover from the BTC BIP 148 fork controversy. The latest ETH dev meeting on Friday confirmed they have no plans to address the the increase in block times and difficulty due to the programmed ICE AGE before the Metropolis release later this year and are also planning to REDUCE the block rewards before then as well. This means at the current price, ETH will no longer be profitable to mine for most people by the end of August.
