The year may be difficult to restore investor confidence because there is no security for the ICO and is often carried away by the team, but I do not know whether in the future anyone can overcome the fraudulent ICO.
in fact it is not too difficult to restore investors' confidence, I am sure they will come back to believe if you are an institution that guarantees the security of investors from ICO fraudsters by tightening an ICO project launch.
For Securities, we have SEC to regulate and give more restrictions over the ICO and fake exchanges and many more. Please look after the what are the regulations publish by them.
If you personally worry about the fraud ICO projects, you are always welcomes to share it on scam accusation. It will be help for DTs to check and assist you.
