This is Exchange Website Source.
Currently, the BTC/USDT is working in example.
This is .NET source.
I am offering only source for now.
If you need to use this source, you have to know about .net knowledge.
Also, you can hire any .net and exchange developer.
Or, I can work to installing after this source is sold.
Of course, there should be installing services too.
