Hi, there are some CryptoCurrencies that are not included in the currencies.json file. If you could please take some time and add them in one of your next updates that would be great!
These, at least, should be included and are not:
Crypto.com Coin (CRO)
Binance Coin (BNB)
and these stablecoins (all regulated and must be included)
USD Coin (USDC)
Paxos Standard (PAX)
