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 ?
I think it will last a long time and will not change in the near future as long as many countries prohibit bitcoin as means of payment, so peoples prefer credit cards for their payment of online transactions. Peoples only can use bitcoin as a form of investment because it is more profitable for short term or long term.
