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 ?
Well, bitcoin has failed as a currency since its all about the investment and some profit making. And it is not the original purpose of bitcoin creation. Hence, many crypto enthusiasts prefer more to use bitcoin for investment. And instead of payment method they are more fun in investments. I believe that bitcoin can only perform as a currency if some holder and inventors will decide to use them as a form of payment.
