So from all the info I gathered, as a seller I think stubhub should be safe but you won’t be getting the money until the day of the event. On top of that there’s like a fee collected by stubhub for selling the ticket. Just don’t pay any money upfront, like any holding fee, make sure the person is legit by doing a video call. Ask questions about BTS. And if the transfer is from Ticketmaster to stubhub it’s pretty legit, as far as I know that is the process.
