[Feature] Json structure change proposal

[octavioamu]

Feature Description

When adding new tokens to the endpoint the front end need to duplicate code making not DRY
To solve this I propose a change on the json structure to make pairs of proprieties, example of possible format:

{
  "balances": [
    {
      "symbol": "ETH",
      "count": 138714.89847312044,
      "price": 3746
    },
    {
      "symbol": "BIT",
      "count": 1000000020,
      "price": 1.8032047833
    },
    {
      "symbol": "xSUSHI",
      "count": 2132234.813768734,
      "price": 12.7604923276
    },
    {...}
  ],
  "usdTotal": 2434324234234
}

Current structure changes the names of the property making hard to create more dynamic and flexible components:

Additional Information

This task need to be coordinated with front end changes to avoid any break logic
