Bug: BDG/BTC Pair displays 0.000000 in CoinPrices component

Temporary workaround could be to remove some lines of code around [here](https://github.com/onitsoft/nexchange-open-client-react/blob/c75b97d3f1409c313da579eadb2d9ed0edf4aef7/src/components/Home/Hero/CoinPrices/CoinPrices.js#L109) (in other words, to stop displaying this pair).
