sure difficulty will rise, by your definition everyone should just stop mining...
the little sc is half the ghs / w of the "normal" rig, and costs half
hense the ROI is the same.
your statement seems to be "its less performance so its useless" wich is friggin moronic.
"As difficulty rises, the performance has to rise" so that doesnt apply to cpu mining or gpu mining?
not everyone is pumping and dumping eather. some acctualy want coins.
now stop trolling.
My good sir, you forget the obvious. That no one bought their lower end rig to earn a mere 20 cents a day. (Unless they are totally hardcore in support of the BitCoin network)
The lower end your hardware is, the sooner it will become marginal profit. There is
no debate on this IF the following conditions are true:
A) The ASICs collectively ship after Block Halving from all vendors.
B) The volume of High Gh/s products reaches the BitCoin network in progressively larger number and raise the difficulty sharply over the next year.
C) The ROI period of time is significantly stretched out by B and A.
People, we are only talking about ROI. This means you make back the money you actually spent @ your vendor....we aren't even talking about
positive profit. By the math above 700 days to recoup that money is insane. 20 cents a day is insane.
There is a good reason why I mentioned a specific vendor basically admitting they were selling lemons to their customers. If they were touting energy efficiency and marginal returns as a selling point then that means they were fully aware of what their customers would eventually realize on the lower end of their product offering.
---------------------------
At the start, while difficulty is low, people will likely be quite happy with their low end purchases, but as difficulty guts their returns, they will definitively be crying to high heaven that it may take up to 2 years to make back the cost of a Jally as the margins rapidly shrink. (assuming electricity costs remain the same, which it may not considering world issues.)
That people don't realize this either means they haven't thought that far ahead (I have at least!) or they are "friggin moronic" to use your words.
You think you know what a troll is? Wait until the majority realize the lemons they have bought. You get what you pay for.
This isn't coming from a crystal ball. It's common sense if you evaluate a number of different factors. Are you even looking at the returns on some of these products? If you are perfectly satisfied with marginal returns then there is nothing wrong with this at all. You just have several hundred days until you ROI is complete.
The money (or BTC) will come "fast" at first with a low end device, then gradually slow down to a mere trickle. This is likely before you recoup 100% of your investment. So its like throwing money into a furnace with a low end device.
The good news is, if people give up in that span of time and shut off their rigs, or if you resell your rig in a second market to recoup your costs in a reasonable time frame. (reasonable for me is far less than a year)
