WE already know that if you've created the so called "next bitcoin" you do not have to market it as such. It has to have a legit use case, as well as mass adaptability.
People and real investors are already tired of this BS. The next BTC as they always label it will no longer be liked by the community. Even adding bitcoin at its name will never do anything differently. So, for those developers that have made such projects, they know that it's nothing anymore and they're just wasting all of their time in creating those kind of Bitcoins when there's already one and thought that it will become a good project that will be invested by everyone.
