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 nowadays people are getting crazy for Bitcoins by investing in them as an asset only and they are not using Bitcoins as currency... Actually people are greedy enough to make profit anyhow so people are not accepting Bitcoin is currency brother they are investing in Bitcoins keeping it for long term investment or trading it and making profit.
