The major difference that it would have made is to reduce the scam rate that people suffered and also make it easy to tract and hunt anyone that tries to exit scam because an exchange is involved.
I think it's not a difference, but a new strategy to make investors believe in the project, but in this case the investors are also smart enough to give their trust to the project, even though the strategy made by the team is quite telling.
for now, it is not enough to attract investors. but how to make investors really believe is difficult for a new project to get. They are serious and committed to market planning that will earn investors confidence. We certainly know how the current investor orientation is, of course, the focus is on the market, not only on product development.
