Go live your dream and work whatever model you choose and disclose. There will be obstacles all along the way. Everybody successful and well-known trader started somewhere. Every failure also started somewhere. If you can demonstrate results investors will beat a path to your door. You can literally buy a hedge fund in a box start-up package. A public fund will be a tough expensive path, but you're in Europe and you'd be amazed at what you can in the smaller countries and on their exchanges - especially if you just want to list and do sell shares.
