from every side, fraudulent projects almost killed the entire cryptoqurrency space including project investor confidence. actually not only now, but fraud projects have existed since then and still continue today. we can't eliminate it completely but we can still avoid it by not participating in suspicious projects.
Scams are not going to kill the market of cryptocurrencies what it is going to happen is that the scams are going to kill the market of icos and any other similar market that emerges in the future.
And while that is a shame since there are talented developers out there that could make use of our support if they are really smart then they will need to find a way to profit from their idea without the need to have to create an ico just like satoshi did when he created bitcoin.
