Hello!

Tryed the exchange and i dont understand what the payment ID is, shouldnt that be handled programmatically? I dont know what to do with this or where to place it...

Also the Buy orders should be on the left. (I know its only a detail but it look better and almost all exchange have buy orders on the left and sell order on right)

Look good so far!

Great work crep team!
