In one thing I'm sure, everything is replaceable. I don't wish to say that bitcoin will replace fiat, I wish to open conversation about how much is possible bitcoin to do that?
I remember Germany has Mark, Italy has Lira now they have Euro. Tomorrow everyone can have bitcoin, or something else.
When I think about future I get confused, and its hard for me to make any predictions. I guess I will enjoy the moment.
Firstly, the estimated total number of Bitcoin limited. According to forecasts, mining Bitcoin can finish in 100-150 years. The population of the earth in 100-150 years, will increase many times over. Vryatli Bitcoin will be enough for all people. Is it worth doing at all money exchange. Secondly, even if the euro replaced in many countries, the national money. Nonetheless, many people refer to this change is not always good. And in the third, you are doing the right thing that you live here and now and not think about too much. It is unlikely that excess, bad thoughts are good for health.
