Take a look at ConnectX, its' a private network of small satellites that stores digital currency wallets and performs financial transactions ‘off-planet’ eliminating the use of the Internet. Looks really promising to me.

You can buy coins for 0,15 cents each in the first phase, which is still going on.
The last phase they sell their coins for $2 dollars each.
And there is a airdrop going on right now. You can get 25 free coins($50) by joining the webinar.
