A very good idea that can certainly generate a lot of buzz and interest from people all over the world. The only big hindrance is the possible cost of such a venture because I am sure nobody will allow any name to be painted on any surface without first talking on budget. Sending anything to anywhere outside of Earth can certainly cost millions of dollars, if not billions, and I am sure nobody will be giving Bitcoin a free ride. Besides, Bitcoin is not actually so ready for a massive adoption or for it to become a global currency. There will be an imperial stretch if that can happen. So let's instead take things slowly and always be patient. Now, having said that, this is just my opinion because certainly nobody is stopping anyone to dream big, to dream beyond Earth and to take the name of Bitcoin to the moon and even to the stars.
