Well, Blockchain, unfortunately has became more of a "get rich quick" scheme for few crooks. Thus, whenever we hear "ICO", it sends warnings to our brain.
But it does not mean, we cant make money out of it. As long as we do not end up like Bitconnect shills. (you all know who)
But I am really hopeful about blockchain technology. I hope we come out of Proof-of-Stupidity and have real practical use cases more. I expressed this feeling here.
