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??
If you are talking about the scam projects that convinced you, there is nothing you can do about it, being a new market, expect all sorts of people to exploit the new system and that is what happened here with all the scams we have seen in this market in the form of ICO and millions are lost because of that, majority of the projects were scam or never fulfilled what they set out in the first place, bitcoin will sort majority of the problems and hopefully we will see legit companies taking the space and coming up with products which will solve certain issues that can be resolved by this innovation.
