Hello Marike,
This token is indeed eco friendly and ethical. It uses a new financial model created by Richard Heart that uses saving and a rewards instead of mining to secure the HEX network (unlike mining which can use lots of power and be centralised to rich mine owners). Check out the video as Richard explains it better than I ... but if you do hold BTC you can get truly free HEX tokens (10% extra with my link) which are highly likely to rise by 1000x if the maths is correct, and it does appear to be!

keep well =D
