Making your own coin is not something to dream about, in fact, you can easily have your own coin and name it whatever you want with minimum effort and that why the market if full with scammy and bad projects. Before dreaming about have your own coin you should have a real project so your dream should be about your project not just have your own coin. You should have a project and an idea you plan to achieve, you should have a team behind the project, you should have strong developers, and then you can start thinking about your coin.
