The Cryptocurrencies Exchange System is a console-based application designed to facilitate the trading of cryptocurrencies between users. The system models the core entities of a cryptocurrency exchange, including User, Crypto, Wallet, Exchange, Order, OrderBook, and Transaction.
To run the application, simply execute the main method in the CryptoExchangeApp class. This will initialize the system and allow you to start interacting with the exchange.

- User: Represents the users of the system.
- Crypto: Represents the cryptocurrencies available for trading.
- Wallet: Manages the balances of different cryptocurrencies for each user.
- Exchange: The entity where users can buy cryptocurrencies directly from the system.
- Order: Represents buy/sell requests made by users. Orders act as tickets waiting for someone to fulfill the user's request.
- OrderBook: Keeps track of all active orders and matches buy and sell orders.
- Transaction: Records completed trades between users.
The Currency class uses the Singleton pattern to ensure that each currency is instantiated only once throughout the system.
Used in conjunction with the Singleton pattern to create and manage instances of different currencies.
The application is structured using Hexagonal Architecture, which ensures a clean separation between the core business logic and user interface.
