You can't blame the investors to see most of the ICO'S as a scam because you know how many ICO'S became scam in the past years.
Instead of investing in ICO, I think its better if we will just invest on IEO'S. Its more trustworthy especially if it is being launched by a reputable exchange like Binance.
I agree that the IEO may be the next generation that new altcoin has to go into. However, efficiency and success have to wait. It is too early to say anything, especially when IEO projects can also evaporate after a few months like previous ICO projects. Everything needs to be adjusted over time or an open space from the market.
