It takes around 1 year to ROI on the GPUs now..
Is that taking into consideration the resale value of a GPU?
I find many people do not take that into consideration when making the decision to GPU mine Alt-coins.
What I mean is: if you spent 2000$, it takes around a year to get the back. Then you can sell the hardware for profit?
You are correct in terms of ROI.
I think of the GPU hardware in terms of an asset with a certain rate of deprecation.
In terms of a average small investor/hobbyist I think it is important to consider that risk is mediated by the fact that GPU's are for the most part an asset that is easily liquified. If the alt-coin markets crash and the investor wants out, they can recoup a large portion of the original investment. Figuring out that tipping point where they could reasonably sell the GPU investment and not take a loss should also be considered.
