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 think we can not say it now for the future is still a bright with bitcoin. For now bitcoin is high volatile, but I still believe in the future of this, bitcoin will be a major currencies in the future. We will see it.
