No it isn't. The energy spent on mining is gone. I can't run a vacuum cleaner off a Bitcoin. Batteries store energy, Bitcoin is only a vote on how to spend energy in the future.
The disconnect is obvious every time the price of Bitcoin changes.
The price of Bitcoin? What do you mean? A Bitcoin is a Bitcoin. What it will buy will always increase over time.
