I recommend being very active in slow castings, if you make it far enough you will get a good amount of karma from them. Just check the FAQ at the bottom of the site and scroll down to the game prize table.
Doing well in games will get you some T$
also when you get yellow level you can bet on rookies games and safe bets like charity games are an easy way to earn T$
don't worry too much about T$ at white tho they will come with time
