yes you are right for now it seems like there are a lot of scam projects, you should be careful to choose an ico project and make sure you have the skills to analyze from the team first make sure the team is genuine and really can be contacted and state that they did make an ICO .
I always look the exchange position of a project. I never invest in those currencies which are not listed in exchange, because most of such coins are fraud and will disappear from the market after collecting huge funds. I always invest in reliable coins like bitcoin, Ethereum, Ripple etc. these are the best cryptos in the world and are guaranteed and my money is safe here.
