Being a Crypto currency lover for a long time . I loved one thing people believing on solution or Solution for the problem using crypto currency . Not only believing even they were investing . But i found lots of solution were just fake promises . Lots were submitted big white paper with lots of hopes only with the intention of raising funds . Do you find any currency really solve the problem??
It is very strange that you summarize all the projects in your question. It is obvious that the cryptocurrency is somewhat ahead of its time, and it is not always possible for it to find a convenient place even when your project really understands what it wants to realize, it simply may not be in demand because the time has not yet come.
