I sense contradiction in your criticism.
Bitconin like Gold, does not generate cash flow and has no equivalent conversion. How to measure it's true value.

How is Gold's true value measured then?
Secondly, has gold ended?
I will recommend you read about gold mining and bitcoin mining.
Then, you will appreciate the importance of bitcoin and know that all you require of it lies in the mining power of the people.
Any commodity that is sellable and buyable remains in the circle.
The phase or challenge bitcoin is facing is the general acceptability which is a major attribute of a currency.
