Virtual currencies have become very popular among people who like finances since currencies like Bitcoin started to become used to exchange real money with virtual currency money.

Usually, the exchange process between currencies is done by broker companies.

This package implements a simulation of a cryptocurrency broker system.

With more development work, it can evolve into a real cryptocurrency broker system that actual broker companies can use.
