i wonder: if Bitcoin will become the main coin, what will happen to the money we are using now like us dollar?
It is quite unparalleled to what might happened in the future but seems it was open for discussion, I would like to add my opinion on this one as I have this ideology to informed the uninformed.
(IF) fiat currency (hard paper money) will be replaced with bitcoin are you willing to shoulder the taxes for it. Because that is the end result of it because the government must produce something for the economy. So dont asked for this kind of bargain if you will complain in the end.
(IF) fiat currency will be worthless, we can display it in frames and hang them around our house. Or you can even used it privately(you know what I mean/like tissue).
So (IF) this idea is not good to bitcoin users like us, so it is much better that it will remain deCENTRALized for long.
