Has someone already asked for a refund at this late stage of developement?
Boom! Another one bites the dust.
Those who ask for a refund now at least get their investment back, those who don't will be most likely looking at a negative ROI. Gonna be interesting to watch.

Refund = 100% ROI within days
Mining = 100% ROI in 4 - infinity months
what econ class did you take? that's not ROI that's simply getting your money, back, breaking even. There is no ROI in term of
BTC gained unless you are mining lower difficulty alts and selling them for a good price on the exchange.
+1000
THANK YOU! I keep saying this. ROI does NOT equal breakeven. If it mines, AT ALL, you've "made ROI". Negative to be sure, but still a return on investment. Refund doesn't even equal breakeven necessarily, depending on exchange rates.
I'm going to suggest something here, and perhaps start a separate thread a little later. I think it would be a good idea for miners to invest their BTC in off grid power solutions. There are literally hundreds of ways to generate power. And as an added bonus, you could take your whole living space off grid if you do it right, or big enough. It's not truly "free" energy, as there are equipment and sometimes fuel costs, but it can be done where your non recurring costs will make you money vs. the grid in fairly short order. I don't know about other countries, but in the US if you produce more than you use, you can feed it into the grid and the power companies have to buy it by law. Even without the law, they still would as their generation capacity is always under pressure.
Something to think about...
