Bitcoin was supposed to be used as a currency, not only a form of investment. However, it's been more successful as a form of investment, a "speculative asset".
Do you guys think that this can change in the long term ?
I strongly agree. But I think bitcoin doesn't fail to fulfill its function, being a digital currency, because even though most people see bitcoin as an asset, some of them still use it as a currency. We cannot change that fact.
