Nice post.
This is the first I've heard of this, so thank you for sharing.

While there are many stats here and your post has lots of information about your results, it does nothing for explanation of service or procedure. My limited research done between reading post and replying to it has not answered any of my questions either, so I thought I would ask you, since you obviously have experience with it.

To start, you just donate to @coin-doubler and they start paying back the next day?

Do I need to leave a note of any kind? Is there a minimum or maximum donation cap?

Is the paypack time period a set interval or does it vary depending on size of donation?

What I mean by that is, if I donate a small amount, say 10, is that amount going to be locked up for 58 days or would that amount be paid back pretty quickly?
So, based on your donation size, it happened to take 58 days to be paid back?

Sorry for all the questions and thanks again for the info.
