Dear hodlers, I have some junk products to sell you, all you have to do is bring in more people to buy your stuff and you have to buy my junk at a premium. Doesn't this sound like an amazing opportunity to buy a Lambo? I will be the first one to buy a Lambo though, you just have to hodl 
Ironic, you want to say bitcoin is a titan scam but people already knew it's not. We see lots of economy professors are investing in bitcoin. They also explain bitcoin on tv shows. Then saying it's a junk is only invalid.
I wouldnt want to say the protocol is junk, because it is really innovative stuff, the coin however is completely worthless.
That is not what the market thinks. It has attributed it value of around $70 Bn. For a "completely worthless" coin, that is a fabulous market cap. The protocol is definitely awesome, but none of the copy cats have come close to this market cap.
