Bitcoin is just object of investment. It will not solve all global economic problems and will not bring us more freedom than the electronic payment system. Yes, in some ways it is more convenient than the Fiat
Believe it or not, there is actually a fair amount of legitimacy to the statements about Bitcoin freeing people more financially speaking. Due to the lack of a governing body that directly controls (and manipulates, by proxy) a currency, the individual maintains a lot more freedom and is able to make more of their own economic decisions. These are things not typically found in a majority of other currencies.
