ICO are over and its new era ,era of IEO totally its the same i mean the same projects they just have changed the way of fundraising so if you got good to invest in the project then no matter its and ICO or Ieo, its worth if project is legit and real-life working.
The problem is that most of the good project are using IEO because they got indirectly advertised by the popular exchanges. The good project will have no problem doing verification and many things because they are legit unlike the fishy ones. It's like a filter for legit project and not. Although I'm not saying that all ICO is bad. I'm just saying people prefer IEO nowaday.
