If it was easy, they would have already done it. For the most part, I would not be too concerned about your IP. It takes so much time, effort, money, the research you want to do etc, that it is not very likely anyone will take your idea and run with it. Of course, this answer is with no knowledge of what you want to build, and yes some concepts could be easy to replicate. But competition is a good thing! You just have to better, faster, know your customer and deliver quality. With your current thinking, you'll face the same dilemma when you (beta) launch.
