binkle (nprofile…87ru) I'd say one threshold is saying you'll stop doing something if you don't get money. "If I don't hit the goal, I can't justify another video!"
Another is asking for money for something completely unrelated to what you're doing. "Got into a car accident, I need $500 for repairs." "Anyone able to donate $50 for groceries?"
A tip is a reward for something you already did, or something you are planning to do no matter if you get the tip or not.
