It s very common thing that when something becomes a success everyone copy cat it and tries to benefit.
The catch is that at this point in time, the “new” idea is no longer new and the main differentiator would be price… Lots of hard work for little earnings.
A better approach is to become the leader that creates the trends, the standards by which everyone else is measure and the return is much greater.
Then again, many people may believe coming up with new products, innovation, being the leader is too hard, it is for supper smart people, etc. The reality is that inventions, innovative thinking is a lot easier than most people believe. For example, how many time there is a new product in the market, you see it and you say to yourself “why didn’t think of it before?”
The main thing here is to believe in yourself, believe you can do it!
