Hey, everyone's free to do what they want, it's 
impossible to control the world -- but it's 
understandable to be irritated with speculators. 

I've never heard of a case where this sort of 
behaviour actually helps a market, be it (damn, 
this has to be my favorite example) tulips to 
comic books or sports cards to Pokemon. When you 
get too many speculators in an area, prices 
increase simply because people think they will 
get more for it in the future. The market become 
artifically inflated, and eventually crashes like 
any pyramid scheme. As seen with the Dragonball 
cel ilovelefty tried to sell, there eventually 
reaches a point where speculators lose money, 
because the prices are too high to accept 
increases.   

Unlike dealers, who actually do something to get 
their cels other than wait around for other 
dealer's updates, I doubt that Ilovelefty will 
try and weather the hard parts out, and will just 
move to another market.
