I shall admit that more and more ICOs nowadays are cancelling their projects, or doesn't reach their softcap. But yeah we cannot blame them for not paying if they haven't got money for development. But scam projects really make me angry
People need to recognize what they are getting into, this is not different than startups, you can work there and receive some stocks of the company and if it is successful you could become a millionaire but if it fails you lose all your time and effort and the same happens here with icos.
