I take the knowledge, lessons and experience the Hive chain gives me...as well as the rewards. I have a regular job so I try as much as I can to be independent of Hive earnings...sometimes you just can't help but look towards it though.
Even if it fails tomorrow; I'll be devastated yes, but I will also take the lessons and experience and move on
I think taking a bit here and there is fine, but if actually looking for this to be an investment, always keep in mind the future cost of spending now. There is a balance point somewhere :)
