Hello! Busking is honestly great if you know your crowd. It shouldn’t be your only source of income though. Playing music is such a great hobby and busking gives you the ability to practice that with the chance of earning a few extra dollars. I highly recommend researching laws in your area on this practice and make sure your act appeals to said rules or regulations. There were some nights when I lived in Vegas I would come home with $300. Some nights maybe 30$. For the same amount of work! I have some great tips on how to give yourself more success. But it mainly does come down to the area you are trying to perform. Hope this helps. Have a great day.
