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 think it's not a failure, it only takes longer until people turn to cryptocurrency. crypto's main problem today is adoption and regulation because both of these, many projects that actually can solve difficult problems to get users on their platform. we can't blame the developers because they can't do anything. the thing they can do is make and develop.
