A short while back I posted that I was interested in buying a megaYAC (1 million YAC), though serious offers definitely weren't what I received.  One person wanted 3x or 4x the going rate on Crypsty and BTER, and another asked for 10x higher than the going rate.

Did you get any actual serious offers to your inquiry?  I ended up just buying that amount on Cryptsy spread out over a bit of time, and then have mined another megaYAC (tm) in the meantime.
