As the market situation improves, we will see better projects growing. But I have no idea that my choice will be ICO or IEO. This depends more on the project itself.
I agree with you. An IEO is no significant difference to an ICO, except that it takes place directly on an Exchange. With every potential investment, it is important to take a close look at the project and the people behind it - regardless of whether it is an ICO or IEO.
We are considering an IEO for the following phases of our coin offering, but this will take some legal preparation over the next weeks. We are targeting the early adopters with our ICO in this phase of the market.
Have a look at our ANN if you are interested in privacy coins:
