Planing to make one international group or platform to trading basically buy and sell crypto ,
Many others are planning too. What special aspects does your plan have that make it unique from the others? We dont have an end to new crypto exchanges coming up be it a market making and taking one or just a P2P one. Look at localcryptos and the older localbitcoins.
as well as cooperate crypto based business....
That is a future prospect for now. But first of all you need have some sort of security for those who are going to cooperate in building this exchange. Do you have anything in mind already or are you having just a plan and nothing working as of now?
lets make a team from different worldwide and new team
I believe they will want to know the budget, that too publicly.
