It all depends on you. If you do your research well about any project and you are convinced about the authenticity of the platform, they why not. Even though IEO is trending, there are still good and promising ICOs.
At this point I can confirm to you that very few ICO projects are operating in this market because if it is a big project, their team will find ways of IEO on big exchanges. I think the ICO era is over and now only the IEO can help investors earn high profits. In fact, many people are more interested in investing in IEO because it is an investment that can make them change their lives
True, all good project mostly prefer using IEO than ICO. They can easily get sold out if the project can get IEO on big exchange such binance.
That's why most investor are prefer investing on IEO than ICO, i think OP should follow this one too. It's better invest on IEO.
