If you give them 100,000 Dollar, you're the one taking all the risks. So they can either double it or loose it - they will still get their cut.
So why handing your precious and hard earned money over to someone else, where obviously there are different interests in play.

And never ever gamble with something that did cost you a lot to build over time.
