Or why not just stop investing to ICOs and just go with the normal tokens / coins that are already listed on exchanges?
Doing research is still good enough to know if the ICO is a scam or not that will give you strength on what to avoid.
May be that can form a good option but not that much good as if it will create a healthy environment for the crypto currencies. I mean if everyone stopped making investment into the ICO then how do you think that new coins which may have greater potential than the current will exits or will be created.
This can be bad and also there is always need to have changes in every field to improve things better and better. So in case of crypto currencies it is the crypto coins which are heart of the crypto world which needs to be improved all the time. Thats why ICO;s should be there.
Now scam and legit are the parts of different story I believe.
ICO must be properly determined first, it's cost time and investment if we choose a questionable project it's a very good idea new coin or brand new ICO but we carefull of selecting the good one
