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 ?
For now, BTC is not yet worthy to be a currency though the original plan was to be a currency. But BTC generates a huge amount of currency anyway which everyone having a BTC love it.
If the BTC become a currency, I guess the value of it will not reach as high as today.
