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.
When binance was launching its launch pad and those exchange sites have not paid a lot of attention to that. but after binance has raised multi-million dollars from its launch pad and those exchange sites are trying to do the same. Binance chooses a coin based on its analyzation while others based on how much paid for them.
