RE: How to invest in SpaceX
we are all to our best to spread the knowledge about the platform :)
and.. we do quite well recently:
if you want to support growth of polish community, you can vote on Polish content from time to time: https://steemit.com/trending/polish :)
Also recently on my 2nd account I started publish list of post (in english and polish) published by polish authors: https://steemit.com/polish/@noisy2/2017-05-16-posty-polakow-na-steemit-z-ostatnich-24-godzin . You can subscribe my @noisy2 account, so you would be reminded about polish community from time to time :)
BTW. did you heard about @strimi? This is also Polish project: https://steemit.com/introduceyourself/@strimi/strimi-it-polish-version-steemit
It should bring couple thousands of existing users to Steemit, after migration to STEEM will end :)
