Whether it's in matters of legal tender or a very high value later.
But what I never agree with is when someone says that Bitcoin will completely replace fiat money, I totally disagree with this. Because at any time this Fiat will not be completely replaced by this Digital currency. But between fiat and Bitcoin, will go together according to their respective functions.
We need to be realistic while thinking about bitcoin. I too disagree with people who say that bitcoin is a complete new financial system that will change the world forever and bla bla. Till date value of bitcoin is measured in fiat like today we are saying that one bitcoin is worth 40k$.
Both fiat and bitcoin have there own pros and cons, and will continue to coexist with each other. There is no danger of both from each other as both have there own domain.
on what they are saying.Bitcoin is for p2p transaction without any intervention and yes it could really be applied in most cases on decentralized manner but there's no way that it could really replaced
into the current system that we are dealing of on years passed even upto now.
