I have a hard time following the logic when people make a statement that Bitcoin will replace all fiat currency. In my world view, they coexist and will continue to coexist. I can see where some fiat currencies die and Bitcoin fills in the gap, but not on a global level. Your thoughts?
They will fill the gabs for sure, and maybe someday the will really replace fiat, as you can't print out as many bitcoins as you want and you can't make fake bitcoin bill.
It's all vertified by computers and the most important, it's open source (mostly) so nothing hidden at all.
