You responded with nothing more than a "See, We warned you, we were right" and point to the current market action as evidence that nobody needs bitcoin, as if the current price is proof of your correctness. Like it makes any difference.
... you're proposing there's a superior method to gauge the value of bitcoin other than the market exchange rate...?

Look up the words "value" and "price" in a dictionary. I know it will be hard for you to believe you were wrong about something, but trust me. It will improve your English.
