The whole card market looks to be a major major bubble right now it's absurd. Cards have doubled, tripled, etc in the last year. People like to say that it's people "diversifying" their portfolio but I think that's a load of shit. I also don't believe a lot of eBay auctions final auction price. I feel like a good portion of them are fraudulent shill bidders.
I know very little about the card market myself and
@JojoTheWhale can probably shove me in a locker and tell me i'm completely wrong. That's just where my head is at.
