I don't really understand this coin. In my opinion (and I have also been thinking about how a cryptocurrency on Mars should work before I found this one), a cryptocurrency on mars SHOULD BE STARTED ON MARS. Not on earth. That makes much more sense, and also with such short block time it is going to be very hard to keep copies of the block chain both on mars and on earth. If there is mining on both planets the blockchain would easily branch into two copies, right? Moreover, mining takes a lot of electricity which will be scarce on mars, it would make more sense to have a proof of stake coin.

I like the idea of thinking about a cryptocurrency on mars, but I don't think (and also don't hope) it will be marscoin.
