Since you have long list why someone needs to invest on your project, why did you choose Probit as exchange? Why not Binance or Bittrex or any other popular exchange? Are you confident that you will attain success from that exchange?
This is like a paid service, Binance being the leader for every exchange it'll be charging high for the launch through them. The large scale project investors with their huge funding prefer Binance while the rest go with these kind of exchanges for the launch.
You are right with binance leading with they own IEO which launched the binance coin which is doing great but investors should know fake exchanges because the same that happened to the ICO market can also happene in the IEO it all depends on the team behind the project.
