Note: While creating Binance service, pass a currency override array to resolve a currency code difference. This is because Binance chose to use the code BCC for BitcoinCash instead of BCH.

let currencyOverrides = ["BCC": Currency(name: "Bitcoin Cash", code: "BCC")]
let binanceService = Binance.Service(key: key, secret: secret, session: session, userPreference: .USDT_BTC, currencyOverrides: currencyOverrides)
