As you know most of ICO's are scam and most of not paying so new trend is growing that is IEO ,i hope in future ICO's will replace with IEC and that is good for investors .
More than 1000 ICO projects are appearing in the crypto market and almost 99% are scam projects. I think these projects should not appear in this market because really new investors may lose money if they do not learn. I personally only believe in IEO projects because it gives investors the best liquidity and makes much better profit than ICO so just choose IEO to help you feel safe than.
Every year thousands of newborn projects appear in the announcement board of bitcointalk forum but an only small part of these projects can make sustainable gains over years. IEOs are not accepted as a scam cutting machine by me, I make my own analyze and invest in that project.
