## Overview

BitTrade is an ASP.NET MVC cryptocurrency-trading demo centered on account access, social messaging, user discovery, wallets, and live currency prices. The main web controller delegates account, user, messaging, and wallet operations to business services; API controllers expose user and message operations. Services use a unit-of-work abstraction for persistence. README documents live cryptocurrency prices, but sampled source does not establish the market-data provider or its exact wiring.

Main entry points: [`BitTrade.DAL/Repositories/UnitOfWorkcs.cs`](https://github.com/david-torosyan/bittrade/blob/master/BitTrade.DAL/Repositories/UnitOfWorkcs.cs) (Unit of work), [`BitTrade/Controllers/HomeController.cs`](https://github.com/david-torosyan/bittrade/blob/master/BitTrade/Controllers/HomeController.cs) (MVC actions), [`BitTrade.DAL/Repositories/Repository.cs`](https://github.com/david-torosyan/bittrade/blob/master/BitTrade.DAL/Repositories/Repository.cs) (Generic repository), [`BitTrade.BLL/Services/AccountService.cs`](https://github.com/david-torosyan/bittrade/blob/master/BitTrade.BLL/Services/AccountService.cs) (Account service)
