I do not know but i think at this moment many people treat BTC as kind of asset to invest like stock. but in the future, when the market is more stable, BTC will become the official currency of the world
It's indeed as you said and regardless of what picture the Wall Street guys and professors may have painted of Bitcoin, what's fact is that Bitcoin doubles as an asset because we're already investing in it and making handsome profits. Nonetheless, we're also able to buy and sell with Bitcoin though the scope is being hampered by instability in price.
At any rate, as the popularity and adoption of Bitcoin remains on the increase, we would likely get to that point where many more merchants would embrace Bitcoin an create the enabling environment for its price to stabilize.
