What's the point of this thread when profitability changes each and every single day, and ASICs like the Baikal-B (although not listed, using this as an example) can lose $0.50 of profitability per day with the way things are going for the miner right now? Doing your own calculations for time 'till return is much more accurate, and it's not exactly hard to punch numbers in, especially when calculators like the Nicehash mining calculator exist, where you can click two buttons and find return times for your electrical rate, etc? Unless you somehow make it so the thread automatically updates profitability regularly, it's really not accurate at all, and the same inaccuracy exists for card pricing, which in turn also messes up return time for cards.
