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?
The only thing that could make it happen would be a collapse in the economy, something unprecedented. In this case there would be a chance that fiat currencies would lose much value, and people would migrate to a more efficient currency. But as we all know, the Bitcoin network is not yet ready to deal with such traffic.
although it is not such an easy job, but still the possibilities are there and if all the people will start buying bitcoin then the supply will decrease and the price of bitcoin will increase.
