Hmm, but wouldn't it be wiser for a tipU customer to delegate the SP for herself instead of making it an investment? If one has to wait for tipU to power down, where is the difference between delegating and investing?

Why don't you ditch the invest mechanism and just ask for delegations? That way the money will stay longer on the Steem platform making it stronger.

I only have a rough understanding of how tipU works, so please be lenient with my (probably) dumb questions :)​
