Perhaps we need smaller units than 1 satoshi?
I agree with you. This is undeniably needed since $1 is not the smallest unit of money and satoshi, in contrast, is the smallest unit of bitcoin. So if that (Satoshi becomes equal to $1) happens, there has to be Satoshi Jr.

if bitcoin worth that high of course we will need a smaller unit than 1 satoshi. for under 1 dollar is also still there? but is it possible to happen?
