Holding a coin is like having a hand in poker. When others play against you, do you fold or not? Sometimes you call and end up losing, and other times you fold, only to find out your opponent was bluffing and scared you away, leaving you unsatisfied.
The key is whether your hand is strong enough. When your hand has a very high winning probability and you are very confident, no matter how much they try to intimidate you, you won't be scared away.
