How to get BTC and ETH prices from Binance in Google Sheets?
Following up on my question.

Leon had a point in his comment, Binance doesn't have USD pairs, only USDT.

I updated my cryptofinance calls to =CRYPTOFINANCE("BINANCE:BTC/USDT") and =CRYPTOFINANCE("BINANCE:ETH/USDT") and it worked like a charm!
