They will go up. Remember like 2 years ago when phats crashed hard, and people were taking up like 70% junk for them? Ya it took like 6 months, but rares will always go back up after a crash.
They crashed because people who play RS are idiots who, for the most part, have no idea how markets work and get easily manipulated by those that do. Thus most people lose money and a few make out like crazy.
