Nobody is even ready to accept bitcoin as a form of payment in exchange to their goods and services either, so there's that. For an economy to prosper or be stimulated, it needs merchants willing to sell and buyers willing to pay; you can't have an incomplete set of ingredients in order to make an acceptable recipe that would work, so the blame shouldn't always be on the holders but also on the merchants. But yeah, since the volatility is acting crazy every time, no one would really want to accept payments as it has a high tendency to decrease minutes after they've received the payment. Most people right now are inclined to use bitcoin as an investment vehicle, so yeah, store of value would likely be the main use-case for bitcoin and cryptocurrencies in the next coming years until the volatility subsides.
