Unambiguously yes! I already invest in IEO. It is very profitable if to participate at such large exchanges as Binance. All projects that came to IEO on this exchange made big profit for the investors. IEO is an excellent opportunity to increase the capital with minimal risks.
I support IEOs because ICOs are not fully secured as there is no counterparty authority or actions in the ICOs so the developer can trap you anytime if he is not a genuine person. Else, ICOs are good but the good ones only. Initial Coin Offerings are the best choice of investors and traders now days because they have believed and trust in it due to the counterparty actions of leading crypto exchanges.
If you go through the market guides, you would find out that many projects that are successful these days are launched in IEOs and this is purely the reason why I prefer IEOs. It has been very instrumental in maximizing the returns for investors as compared to what had been the case in case of ICOs. So yes, you should be part of such projects for good gains.
