Good post, @taskmaster4450 (as usual)! But I don't really get the point of @spinvest. I've read a bit into it, but it still doesn't make any sense. Why wouldn't you simply buy Steempower yourself and delegate them to a project; or use services such as dlease.io. But even then, the max APR on dlease is currently at 17.5%, so how is 20% possible?

But let's say 20% are actually being given out, is there any security that those funds aren't just gone? I mean, you're holding a SteemEngine token from somebody who AFAIK is anon.

Would love to upvote this post, but don't really want to advertise a project which I'm not comfortable with. However, maybe you can clear some of the doubts above.
