Maybe something like Call of Duty: Black Ops 3 does? They had a beginning Challenge which you could complete at anytime and get the prize, which was win 75 games. Maybe something like this;

Daily Challenge; (Insert a Daily Challenge)
Weekly Challenge; (Insert a Weekly Challenge)
Monthly Challenge; (Insert a Monthly Challenge)

The Daily Challenge would generate less TC, maybe 500 or 1k or something, weekly could be like 5k or something, and monthly could be 10k? Maybe it could progress in difficulty as well as time? I dunno, but this seems like a genius idea.
