Hi @namjug-kim please tell me how I can unsubscribe the stream from the websocket in order to create a new one with a different target currency using an instance of your BinanceWebsocketClient class, and if this is not provided, can I extend this class?

The current implementation assumes USD is your "default" fiat currency, and uses convertExchangePair() all over the place to make a conversion if the exchange is configured to have a different homeCurrency. It would be a really helpful refactor to be able to set a currency at the top level of the configuration rather than in every exchange. For example:

trading:
  entrySpread: 0.008

It'd be nice if we could have access to Etherscan-like mapping of addr->name, instead of doing it manually/slowly ourselves https://github.com/flashbots/mev-inspect-rs/blob/master/src/addresses.rs#L112-L188. This could easily be done with the CSV crate, as shown here
