Many scammers are using ethereum tokens and contracts to commit they fraudulent art. I think ethereum itself is good but most of the ICOs build on it are scams. I read online yesterday that 92% of all the Ethereum projects in 2016 and 2017 has failed. Most of the owners of the projects are just interested in defrauding investors and nothing more than that. However I am not seeing clash underway as we still have a long journey in cryptocurrency development.
ETH is a good project and it has obviously given birth to a lot of great smart contracts doing good right now. One thing we have to understand is that Rome was not built in a day and over time the platform would get better. Also, fraudulent act is not something that can be blamed on ETH and I would rather say the investors themselves should be the ones to be blamed for not making proper diligence before trying to invest in any ICO.
This does not really halt the fact that ETH really have some security concerns which has made people to lose their funds in the past and parity just got it even worst recently.
