How to treat cases like CoinBase emitting symbol name 'Wrapped Bitcoin' instead of the correct 'Wrapped BTC', or 'United States Dollar' instead of 'United States dollar'? On idea would be to add a table with alternative names for symbol tickers, so WBTC -> [Wrapped Bitcoin, Wrapped bitcoin, Wrapped BTC,...]
