I personally do all three of them. A little less of the betting, because at that point you can lose TC, but sometimes you have to bet to get the bets of the server going. It will help incourage and motivate people to bet with you and against you.

Also, if someone tells you that they will selfbet like 10k+ tc for a nudge. You should nudge them. With people selfbetting large amounts of TC, it will also incourage other people to bet.
