I'm not really sure to this regarding 1 satoshi to be equal to 1 USD since Bitcoin has only 8 decimals in its extent but I don't really know if it can still be extended though. Is it a but too much with that amount? Because if it does and not possible to extend Bitcoin and let's say Bitcoin has been used globally in daily exchange or in transactions in the world market then the prices of the products in Bitcoin would rise which will trigger the fall of Bitcoin and the reason as to the users to find another coin but I think this is impossible to happen really because it is not realistic.
