I'm sure you know the only reason Bitcoin can't be spent is because of government restrictions, and I think this is what creates the imbalance. If Bitcoin were allowed to become legal tender, I'm sure everyone would spend and hold it like fiat currency.
So, for now, Bitcoin can only be used or treated as a very promising investment, and everyone is holding it to generate profits. However, I suspect they, or most of them, have spent or used Bitcoin for transactions, even if only a few times, including me. Although Bitcoin is banned as a means of payment in my country, I have used it personally with mutual consent, so you or anyone else never know whether they have used it or not, and it all depends on the circumstances.
