We might follows with the reference of return as work with the ICO terms as preparing with the plan as releasing offers of service for public and the listing of token by the exchange.
Those might takes 3-6 months of calendar work with different plan of tasks of completion.
You know that to distribute a token it doesn't have to be listed on exchange. Why do you have to wait for the listing on exchange and cannot pay the rewards right after the end of the bounty campaign?
Unfortunately, I could not find information about ICO details and tokenomics.
What is the token total supply?
What is the ICO token price?
