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 ?
Its all about the progress, people are making more and more coins. For what exactly? if they just use it as an standard web currency for services, transactions, online payments then it could be seen as a currency not an asset for investment. The number of investors are greater than the number of people using it.
