I have not seen any new features in the ICO. Everything is the same as usual how the project carried out the previous ICO. Today ICO can still be said to be reliable but not fully trusted by investors. Because now there are many forms of investment other than ICO. So it is not surprising if ICO is less attractive now unless the project is good.
After so many losses by invest in scam projects, scam ICOs, investors learned lessons themselves. Additionally, local authorities in some nations have stricter managements on ICOs. Together, ICOs have become less interesting for investors. They became more careful with ICOs, but by now they likely repeated their same investment approach in the past (with ICOs) and used it for IEOs.
