Try to pick mods which people will actually duel in and do tourneys with. If you have enough TC to start with you can make mad profits from getting servers but make sure you pay attention to the ratio/odds of bets on each player since this will determine the percentage of profit you get from winning the bet. If you have a lot of money to bet: bet safe and ignore ratio. If you have less than a few thousand TC bet small amounts on whoever has least bets on them unless the bet is stupid and will definitely lose.
You could probably make that much on a few hours on a betting server if it is a good one (if there is just one guy constantly winning with a streak of more than ten then just leave ok, betting for him will only get about 0.0001% profit and betting against him will lose you money when he wins).
it is not easy to make tc, that is the point of it, you got to get pretty good ingame if you have no forum skills. if you are good at art start making heads textures.
