Last year Bitcoin was labeled as the worst investment of 2014, however, bitcoin believers can topple fiat currencies as the widely used mode of payment all over the world. The technology behind it and bitcoin's scarcity can both pose a threat and bitcoin's selling factor. But the question is, can bitcoin really substitute dollar or other currency sometime soon?
Give me some links to bitcoin being the worst investment of 2014 please as i made more bitcoin and money than lost so that is not a bad investment by any stretch.
To answer your question no i do not truly believe that it will take over be a substitute for any main world currency how ever much we would like it to. That does not mean it is not the best way to store your bs fiat easily away from eyes, because i believe it is and will be for a long time to come.
