Even those measures are not really enough, there was time in which if you took the right precautions you could avoided most of the scam projects with ease, but that is not the case anymore, scammers have learned to imitate the characteristics of successful projects to the point that it is impossible to tell them apart and when that happens there is only one logical solution and that is to stop investing in new projects no matter how good they may look.
Still, if we allow scammers scam our investment then it is our purely responsibility, as investing is purely a choice, and people cannot force you or obliging you to invest, so if you invested, without doing a research, then it is your fault anymore and no one should be blame on it, as you are responsible for your own action.
And it is precisely because of those reasons I do not recommend to anyone to invest in icos or in ieos, if you decide to invest in the wrong project no one is going to be there to protect you, any money that you invested is going to be lost and taking into account how difficult it is to earn any bitcoin due to its high cost then it is better to keep it regardless of the promises the developers of new coins could make, it is simply not worth the risk to invest in new projects.
