Hello @achim03
It's interesting that painting you brought to share. I'm not very proficient with Excel, but I know it's a great tool for calculations.
You are right that stake is something that in time brings benefits.
You just have to see it as something long term, which is what many don't see, that in general they want everything immediately.
I believe that staking is only possible once your basic needs are covered (lodging, food, electricity,...). It is a perfect way however to store value and to have this money work for your. It's a long term work but one that can really pay out well. Thanks a lot for your comment!
