Well, somebody sure is.
I was going to say, "That may or may not be true. The 10k paid for a WD 1 CGC 9.9 may have been for an investment, but may have been for a personal collection as well."
But I checked GPA, and the WD 1 CGC 9.9 that sold for $10.1k on 11/14/12 sold for $15k on 11/4/13.

I agree that investing 10k in any modern is most likely fool hardy. It is hard to imagine a scenario in which that makes sense for future profit. It seems there would be much more downside risk that upside. However, that same sentence has been uttered over and over again about WD #1 and keeps being proved wrong.
