I still believe IEO is far better than ICOs. It is more secure and cheaper. But an intelligent and clever investor will not expeditiously invest in such IEO without enough knowledge and without further reading some feedbacks from it. Though there are so much positive reviews about IEO, being careful in every decisions is so important.
IEO is better than ICO in some form, and in this regard ICO too have got more good in it. IEO is in its early stage, and surely when days pass some issues will arise when the entire focus has turned towards IEO. In recent days almost every project has turned successful and further the same won't be taking place. By that time we can conclude the reality with IEO.
The only good thing about IEO is the guaranteed listing after the public sale, Since this will safeguard the investors and ensure market liquidity after the sale. This is 100% more secure compare to traditional ICO that takes atleast 6 months to get listed on an exchange or worst never got listed at all.
