Ok. I asked this in another thread already, but HERE, I particularly do not understand where a lot of you are coming from.
First off, no matter what you WILL achieve ROI, so I have to assume you mean POSITIVE ROI. But even given that niggle, there is virtually no way these machines will not reach break even in a fairly short time, after which your only ongoing expense is electricity, which is not that great of an expense on these devices.
So, those of you crying "no ROI" over and over again, WHAT FREAKIN" TIME FRAME ARE YOU TRYING TO BEAT?

Any frickin' timeframe. Please see here.

I mean really. An ivestment that is likely to break even in less than a year??? That's insanely positive by most any business metric you care to apply! ...
If you don't break even in a year, you never will. Never. Unless conventional difficulty predictions are just a bunch of fud, spread by evol gobment infiltrators.
Total bollocks.
So..in 5 years from now BTC are $10k exchange...explain to me how what you said can be true? Also..how you know that or something similar can't happen? That was the point he was making and he's spot on. At the end of the day the exchange rate of BTC is everything when deciding if your investment in a miner profits or not.
Even if bitcoin is $10k if 5 years, that isn't relevant. At any point in time if your rig cannot earn more bitcoins in a week than it costs in electricity (given that week's btc -> dollar exchange rate) you should turn it off. Why? Because you'd get more bitcoins buying them at an exchange than buying electricity to mine.
Also if bitcoin goes to $10k you can bet your sweet ass that difficulty will rise to match, and unless your miner is one of the most efficient (or you pay very little for power), you will not see profit.
So. If I buy a Jupiter now and mine just ONE BTC with it and BTC rises to 10k I won't be in profit?
Because the chances of a Jupiter actually mining just one coin are remote. OBVIOUSLY that was an example, a dead simple one.
I give up, heads are in sand here...not a gramme of logic.
