Hi Akdx! Yes, your balance is low and if you want to keep Dustsweeper active you have to transfer new funds. You did receive a notification on the 6th of August. You should have received another one on the 11th, but that one seems to have failed for some reason.
You can always transfer a small amount, anything above 0.01, and get a balance notification back. In the near future, we will also make it possible to check this via Dustsweeper's own Discord server.
So far you have received 129 votes and saved a total of $1.48.
