When should we see MSC on some new exchanges ?
I think it will take a long time.
All these exchanges have a "Voting" system where you can vote for the next listed coin. We have tried to get on any exchange with voting but never worked out because the MSC community is small and other coins get more votes. Anyone should donate to get lots of votes on any exchange or we will not be listed. Poliniex listed MSC for 15000$ bounty
