Thank you for your question!

We're communicating with several exchanges to host MJCoin, in addition to the exchange being developed as part of our project.  We will post details about where the MJCoin can be traded as arrangements are made, and please keep asking us questions.  We're happy to answer anything we can to ensure this project is a success. 

Don't forget to read more details about MJCoin in our whitepaper at www.mjcoin.com !
