1. Don't invest in ICO projects anymore, they aren't attractive to investors again, most are scam and projects using ICO can take several years to complete fund raising
2. IEO is the best choice now, buy still dangerous on small exchanges, you want success? Go for IEO projects that pick top exchanges only
After countless scam using ICO projects, IEO was born. There are some IEO that tend to be a scam after the projects regained the trust of investors by having a crowd sale on an exchange but nothing changed. IEO projects today have a lot of risk in terms of investments especially if an IEO is offered on a small exchange. So most of the serious projects go to big exchanges like Binance to gather more trust and participation to investors out there. I think it's better to be safe investing in an IEO that is on a big exchange.
