Currency list improvements

We've spent some time cleaning up the currencies list, and now you can sort the currencies by type:

  • Fiat currencies: e.g. USD, Euro, GBP
  • Cryptocurrencies: e.g. Bitcoin, Ethereum
  • Tokens: e.g. REP, Storj
  • Unknown: currencies from our exchanges and wallets that haven't been categorised yet

If a currency is missing, please let us know.
