There are certainly any number of ticket brokers out there that are making six figure incomes.
Right now I'm limited by capital. Volume could scale higher once you start automating the processes as much as possible and using VPNs to get multiple shots, but I'm not quite there yet. One advantage of doing it at low volume is that you can cherry pick only the best shows, like the upcoming Leonard Cohen show. Unfortunately all my free capital is tied up in tickets already so I miss out on Leonard Cohen.
I know it's unlikely, but if anyone wants to loan me money I can comfortably offer you interest rates higher that beat anything you can get on the market right now.
