This entire topic is sounding like an old way of deceiving innocent people here. Both OP and all 3 replies are from newbie accounts and everything has been done within the time frame of 25 minutes. I am not sure, all the crypto developers around the world are checking this board simultaneously.

In my study, developing a white label crypto exchange might need an office and physical developers and more importantly 3 to 6 months of time. It is a real business unlike any other crypto based things like running a gambling house or coinmarketcap kind of reference platforms.

It would be much better to approach your local software developers rather than looking for online freelancers from unknown locations for the reason of easy evaluating skills on software developments.
