Pyrite can't crash much lower than it is now. I'm guessing it will still be used for truegold, and that alone will keep the price steady. And you know just as much as everyone else, no one is 100 percent certain one way or the other.
I sold off a good chunk this week to gear up yet another alt, but i still have a good bit saved. Yet to actually BUY any, just farm and horde it.
