When a certain model goes out of favor, something new comes out. In the case of token sales, it started with ICOs then comes STOs. A few months later, some people are rushing to join the IEO craze. Just when I thought I've heard it all, two new models came out. Just today, I read about STEO (Security Token Exchange Offering) and OEO (Order Book Exchange Offering).

I appreciate the effort of these people to bring something new to the market but all these looks the same to me. Just a change in how it's being packaged.

What do you guys think will be next?
