Changing currency to Dollar

Update the file cryptowath/config.json and set dollar as currency:

{
  "wallet": {
    "ADA": 1000.0,
    "SOL": 100,
    "ETH": 5,
    "BTC": 1
  },
  "watchPrices": [
    "ADA",
    "BTC",
    "SOL",
    "BNB",
    "DOGE",
    "MBOX"
  ],
  "currency": "USDT"
}

Replace the currency on grafana/provisioning/dashboards/crypto.json. Use your favorite editor and replace all occurrences of the string “currencyEUR” by “currencyUSD”.

       "yaxes": [
         {
-          "format": "currencyEUR",
+          "format": "currencyUSD",
           "label": null,
           "logBase": 1,
