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??
I do not think that cryptocurrency failed to deliver the solution.
I think that people do not understand the solution. The solution doesn´t mean quick money scheme, but slow progress which could replace the classic financial market one day.
