This is a difficult question to answer. In some ways, good ideas are cheap in the startup world because there are so many people trying to come up with the next big thing. On the other hand, a truly original and genius idea is still worth a lot because it is not easy to come up with something that no one has thought of before.
One way to think about this issue is to consider the difference between a good idea and a successful business. A good idea is something that is new and has the potential to be profitable. A successful business, on the other hand, is a good idea that has been executed well. While a good idea is necessary for a successful business, it is not the only thing that is required. A successful business also requires a well-executed plan, a talented team, and a bit of luck. Thus, while a good idea is important, it is not the only thing that determines success in the startup world.
