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 ?
Yes as we can see nobody is accepting Bitcoins as a currency.They are accepting it as a thing which can be traded and made some profit.. Everyone forgot that its a currency and nothing else.. Though its price varies time to time.
