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 ?
We cannot easily conclude from what we are just seeing right now. There are many things that may happen and may somehow change your point of view. Bitcoin is not just used as a currency, as we all know ,bitcoin is a digital cryptocurrency which only exist in the digital world. Since it is a product of technology, change is inevitable and bitcoin is not exempted from that. Before it was just used a currency, well now it can also be used in earning which is not a bad thing.
