Can you please answer one simple question: how can you utilize bitcoin, or in other words, what can you do with Bitcoin besides transfer it to another person? When you answer it you will grasp the full stupidity of links you provided.
Your argument seems to hinge on this single premise: That bitcoin has no intrinsic value other than something for people to trade back and forth.
If you look at every non backed currency in the world you will see the same thing. No value other than as a "product" to be transferred between people. Bitcoin is only a scam as far as pretty much every paper currency in the world is a scam.
