What if bitcoin gains much more value than you anticipate? So what happens when 1 satoshi reaches the price of 1 dollar?
What kind of arrangement is made if payment is requested as Cent? Can the bitcoin core be modified?
what you are asking has been asked and discussed a thousand times, next time try searching first.
this scenario is not going to happen for many years, if it happens at all.
and in case something like that happened the code can be modified to have units smaller than satoshi. and with a fork the problem can be solved.
bitcoin core is a wallet, what needs to change in this hypothetical scenario is the bitcoin protocol.
That's what I wanted to learn. So this kind of update does not affect the bitcoin's working system, right?
I am new to bitcoin and mind other questions are coming.
