Not bad, but I'm not sure I buy the parallelism because, although bitcoin was created as a currency, it is hardly used as such. It is often compared to the asset market, with a total value of $900 trillion, which I think is more accurate given the current state of affairs.
Bitcoin is everything though. If people were using the USD more as an asset, would that make it stop being a currency? Not really. But yeah it should be also compared with the assets as well, not just the money supply.
The future will make everything right, imo.
We will see how everybody will view BTC in the time to come, but as for now, I agree with the fact that BTC is seen by most as something to speculate on, rather than a good alternative.
How the majority sees Bitcoin does not change what Bitcoin is though. I use it as a currency and as an asset. It is up to the individual how to use it.
Bitcoin has all the chances to become an alternative to fiat, a true alternative, I mean - not to destroy it, but to accompany it for those that understand BTC's strengths and values.
It already is for certain groups of people.
