Is it posable for a betta to swim to the bottom of a tank and stay there?

Oh, dude, anything is possible in the fish world. Like, bettas are known to be pretty chill fish, so if one decides it wants to hang out at the bottom of the tank for a bit, who are we to stop it? As long as it's not doing the fish equivalent of binge-watching Netflix down there, I'd say let it do its thing.
