The scroll has no bottom on purpose. You have to build the floor yourself.

Older things ended. The show finished, the page ran out, the paper closed. A feed is built specifically to never hand you that moment, because that moment is where people put the phone down. With no natural stopping point you stop when you feel bad or when something interrupts you, and neither of those is a decision you made.

Decide the stopping point before you start. A timer, a number of minutes, the end of the bus ride. It feels arbitrary and it is, and it is also the only floor that will exist.
