Despite the scary fact from Bitmex as long as investors and developers don't get an alternative crowd funding option that can offer investment security and immediate exchange liquidity then IEO remains the only option forseable. I have seen some adverts on Initial Model Offering (IMO) which entails perioding investment of a particular project after passing the investors appraisal mark but the fact that this model also locks 90 percent of investors token which will be release through out 366 days also makes it less desirable for investors. So we are stuck with IEO till further notice
