SubscribeToSymbolMiniTickerUpdatesAsync: no invalid symbol exception is thrown

[BobMakhlin]

When I pass invalid symbol to the SubscribeToSymbolMiniTickerUpdatesAsync method, no exception is thrown:

BinanceSocketClient socketClient = new BinanceSocketClient();

CallResult<UpdateSubscription> callResult = await socketClient.Spot
    .SubscribeToSymbolMiniTickerUpdatesAsync("XRPXRP", response =>
    {
        Console.WriteLine(response.LastPrice);
    });

Console.WriteLine($"Error: {callResult.Error}"); // null
Console.WriteLine($"Success: {callResult.Success}"); // true

I am passing "XRPXRP" as the symbol. As you can see, it's an invalid symbol, so here we should have an exception. But nothing happens.

This is how Binance has implemented it. It doesn't return an error if you try to subscribe to symbols which don't exist. Not much I can do about that.

I understood. Thanks!
