It's my opinion that you are the one that got matters upside down. Your post simply reveals that you don't understand the mechanism of how one product overtakes another product.
Oh, ok. So why don't you just explain it to me, how one product overtakes the other and disprove my argument. Where is your reasoning? I can only see claims...
I didn't even talk about one product taking over the other. I talked about two or more products being used simultaneously and thereby driving their value down alltogether.
Before I start adressing your other points, start explaining to me why you believe that the other digital currencies failed to gain traction and why you think that it doesn't contradict your theory.
Which other currencies are there who "failed to gain traction"? What about Litecoin?
