A couple of things about this comparison:
*A car is a deprecating asset. A car gives utility (the ability to quickly move from point A to point B), which over time, removes the value of said asset. Except in unusual circumstances, someone buying a car is doing so for the utility, not for the hope of it increasing in value.
*I think most reasonable people who invested in NastyFans expected to have returns in terms of BTC, not USD. This is true for all investors in mining equipment. Mining equipment is illiquid, and as such is going to generate higher than /BTC returns for people to continue to invest in mining equipment, otherwise people would simply invest in bitcoin.

I think some reflection as to why NastyFans has performed the way it has since its inception is in order. What happened to cause the price of seats to go down so much? Like cars, mining equipment is a deprecating asset because they will generate less revenue over time as the difficulty increases, however mining investors expect the mining revenue to make up for the lost value in the miners.
