Interesting point of view.
I'm on exactly opposite end - I'm going deeper with ICO's this year.
Your points are pretty valid, but this mean you just need to be more peaky where you are investing. And I'm always and only buying during the pre-ico phase, avoiding those ICO's with massive pre-sale.
Of course, now in my own opinion I don't think that this is valid enough for me to quit on ICOs, there are ICOs that are reliable out there, you really just have to be picky on finding the ICO that will fit you and your standards, and I don't think that the ICO would adjust onto you, you will be the one that will have to adjust on making your investments, I hope that after what you have said and what the community has responded to you would make your mind up and go back to investing in ICOs.
we know that every investment has a risk, so does the ICO who has the possibility of scam at the risk, so it's natural that someone is regret and sad when the risk occurs to him. right what you say, this risk will remain. You just need to be selective and picky in sorting out the potential ICO
