Can Bitcoin profitability mining calculators be considered accurate when it comes to powerful ASICs?
I mean, the problem with it is that when you plug in values for TH/s, i.e. 1,000,000 MH/s, the calculator shows that you can mine a lot of Bitcoins in a day. But, isn't there a limit to the number of Bitcoins that can be mined in a day or even a month? It would follow that those considering putting money into a powerful ASIC miner should consider this limit and understand that they won't be returning as many Bitcoins as hoped and will be harder pressed still in recovering the initial sunk costs.
Does this make sense to anyone?
There's really 2 problems with profitability calculators... they either give you a rosy feeling with no consideration of Difficulty increase or you have to punch in an unchanging increase that soon spirals out of imagination making everything seems like junk in 6 months.I mean, the problem with it is that when you plug in values for TH/s, i.e. 1,000,000 MH/s, the calculator shows that you can mine a lot of Bitcoins in a day.

While 'technically' there is a cap of daily BTC, 144 blocks @ 25 BTC (3600) under optimal conditions, with the network growing by leaps and bounds lately, we're have days where over 5,000 are being minted. A soon as difficulty retargets it will drop down closer to 3600 again. So yes, there is a limit that can be mined each day/month, and if that is exceeded the difficulty changes to a point where that should be the limit.
