Loading

• Category model is based off the one used in by CoinMarketCap.
• Currency model is based off the one used in CoinMarketCap and uses Quartz.net to update the data
• User and Role are children of IdentityUser and IdentityRole which come from Microsoft.AspNetCore.Identity.
• User is connected with a many-to-many relationship to Role via the UsersRoles table
• Currency is connected with a many-to-many relationship to Portfolio via the CurrenciesPortfolios table
