Maybe not that percentage of scams, those who wants just to run away with your funds, but a lot. I truly believe they will sooner or later pay their price, it is not hard to find out who has collected the money and where they went. However, you are not likely to receive them anyway.
I would say the most project are just worthless or doing a project with no hope for the success. Would they ever ever put their funds into that, I really doubt so.
The market will be more regulated and the entry level will be higher, where you need to spend some for legal documents before you are even allowed to collect any. Otherwise, you will face all the rigour of the law. I could be wrong, but that's how I currently see it and who knows how long it may take.
