Soon we will be on Mars living, surviving and propagating. A thought which is as compelling as displeasing. Compelling to be on another planet and see the Universe from another perspective, but scary to think about living on a different planet than home, Earth. However, if now we will establish a society on Mars, what currency should be used?
Cryptocurrencies can bring to the table
If you are going to inhabit a planet, the fundamental components of society have to be implemented for example what we are going to pay with. The difference between Earth and Mars is going to be the countries because it's not a country which will be first to Mars, it is probably a company like SpaceX. The people living on Mars will not come from just one country. They will come from different countries with different currencies. Therefore, a universal currency should be the logical solution (like Ethereum, I got some :D ).
With, lets say Ethereum, the trading around Mars will be much more smooth and faster so you don't have to use your own country's currency. The trading to Earth will be much sufficient as well.
In conclusion, when we are going to establish a society on Mars, these fundamental components are important. Cryptocurrencies are much more efficient and adaptable which we also have to be in general to conquer Mars.
