Ok here an explanation. at first the decision for a coin swap was made because it was easier for the coding. After the coinswap there are two differenct coins.
 Tradecoin with POW, and Tradecoin with MN but both coins are running on a different chain. the new MN trade need to be relisted to an exchange. mark will pay for that new exchange. (not sure what exchange, don't expect cryptopia because thats 30k listing)
there is no need to worry just chill and wait.
