How to help teen set up business accepting bitcoin?

I have a teen who is starting a business selling a product she is making. She has already been saving in bitcoin and she wants to accept bitcoin for payments along with other options. But, I’m really hesitant for her to advertise this as the wrench attack is my biggest concern with bitcoin. She wants to encourage other teens to get into bitcoin but so far I have not let her. Just looking for ideas or thoughts.
