Well, there are lots of people I could give my TC Cards. It can be my family, friends, and even strangers. Yes, you have read the last one right. They could be one of your prospects even though you do not know them yet. You could just hand out your card to them whenever they pass by you and wait for them to join under you. Of course, you wouldn't possibly know where they come from but at least, you have gained a person to sponsor.
