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 ?
No, if you are thinking that Bitcoin is not a currency, well you are wrong! due to if Bitcoin was being accepted as payment in other merchants businesses all over the world. And it is also being used for online transaction. Each country had their exchange where they can able to convert their Bitcoin to their Fiat currency. Which means, it is Bitcoin was being consider as currency thru online.
