Hello Hendrik,
to get a higher REP, high Rep holders have to vote you. I have now upvoted you too and your rep went from 44 to 46. It is just a matter of time.
Great to see your investment in Steemit !
I believe in the concept of this token based economy too, so I invested around 30BTC, unfortunately I did it when the price of Steem was at 4$...
I recommend you to join the Steemit Chat so we can connect with you and exchange ideas with you.!
48 now ;)
