We experience and will still experiencing the waves of changes and uncertainty. Will Bitcoin eventually replace Fiat currency? Why or why do you not think so?
Once Bitcoin solves the whole issue with scaling and fees, sure I do not see why not.
But fiat is far too anonymous, corruptible and exploitable. No government in the world would want to replace a system like that. Especially since they are the main ones who can exploit the whole inflationary aspect of it to "steal" from their own people.
The entire business scheme of banks relies on the broken fiat system. So they too would be reluctant to actually replace it with a currency which takes their profits away from them and makes their entire business scheme redundant.
