Is there any benefit to sending out a Bean Bottle from Poké Pelago?

I've sent out a few bottles of 7 beans from the Poké Pelago and received one bottle with 7 beans myself.

Is there any advantage to sending out bottles of beans or is it a gift mechanic for a randomly selected player?


Based on the page for Poké Pelago on Serebii, it looks like this is just to help random players over the Internet. It won't give you any benefit except the joy of knowing that you helped a stranger.

You can also, once a day, send out a Bean Bottle. This will put 7 of your standard beans out and distribute them across the Internet to other players and you will sometimes find Bean Bottles from other players turn up on your game.
