And Spacechain, hmmm good luck to you. The idea is good, but not practical at the moment. You can hope to earn some good profit because it will likely be hyped, but not for the long run.
but why do all billionaires like jeff bezos, elon musk, richard branson invest in space? because they plan ahead for many years. they know space is only to become bigger. just like they found other trends and made billions. i saw an interview with jeff bezos he got congratulated on the recent amazon quarterly success. he said it was all planned already 3 years ago right now he is thinking about what will happen in the quarters in 2020. that he trained this as a habit to look around the corner and thats the reason for his success.
i dont know if there is a use for new, better satellites phones some day, or new better satellite internet, or other apps. and having a blockchain in space does surely sound like a novelty now, but who knows what is in 3 years? maybe satellites will do even more, like better navigation, control drones, aircrafts, or give something that is better than the internet now? i mean there sure will be a need for space apps, new space technology, even for the bigger missions.
also i think trump said they want to start a moonbase so this will also push space technology forward.
and thats only some of the things i come up with. i think visionaires like elon musk, richard branson already think of many more ways this can be used.
the only thing i wonder about is how are they ever going to make money if its all open source? just by printing coins like all the 99% other projects as eth?
