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 believe you are talking about ICO projects and not just crypto currency because there are a very big difference between both of them. ICO projects are projects that are still yet to become crypto currency, they are still at the stage of raising funds and until they are able to raise the expect amount of funds, it haven't become crypto yet.
Crypto currency itself have the ability to solve a lot of problem, we have seen this in bitcoin how it have been able to solve a very big problem in the financial world this is why it will always be the father of all crypto.
