Dude, get your meds right. They will work just fine when their devs add them to this chain. Give'em some time to sort out their stuff.

Joint Statement from Digix and Maker Regarding Hard Fork
Wherever it makes sense to do so, the "true" version of any deployed contract related to the Digix or Maker contract systems should be interpreted as residing on Ethereum (ETH) "pro-fork" chain. Any system updates will proceed as planned on ETH.
We are not responsible for any ETC stolen via replay attacks against our systems. Users are encouraged to be cautious of replays on ETC and to use a splitting contract such as the one published by Kraken to preserve any ETC they care about.
Well if the hash rate of ETC surpasses ETH at some point, they will probably have to re-evaluate that statement
Well thats just hypothetical. That is why i used "if" and "at some point".
