I do. I'm thinking that the sudden rise in bitcoin is nothing more than a few billionaires' game and other people just jumped on board to further extend the height of the bubble. Well what do I know, I'm only invested in the last three years and still not an adept when it comes to trading, but by merely just looking at it, you could tell that it is indeed a bubble and graphs will tell you that. The big question is until when would this bubble continue to grow until it is popped?
