My advice: Be lucky
I swear, it's hit or miss. Sometimes they can't get enough of me, other times they just want to hang out in free chat.
One time, I was perving around Chaturbate to get ideas (I rarely broadcast there), and a lady was talking about how she was camming to pay for her dental work. She said she was in a lot of pain. Well, she got me. I've been in a lot of dental pain before, so I gave her all the tokens I had in my account at the time. Was she truthful? Who knows? It gave me an idea to make up a financial goal like that, but I haven't actually done that.
