As of now, there is no indication that Coinbase will be listing Mars coin any time soon. This is not to say that it couldn’t happen in the future, but as of now there is no indication that it is something Coinbase is considering.
Mars Coin is not an officially recognized currency and is not available on Coinbase. Any claims that it is being traded on this platform or any other exchange should be considered false and highly suspect. Investing in crypto-currency carries a high level of risk and anyone considering investing in this coin should take appropriate steps to fully understand the risks involved.
This is understandable, as Coinbase has only recently begun to list alternative coins on their exchange. They are currently focusing on the top coins by market capitalization, and Mars coin does not currently rank in the top 100.
However, this could change in the future as Mars coin continues to gain traction and grow in popularity. Only time will tell if Coinbase will eventually list Mars coin on their exchange.
