      Expected model structure:

        key         [string] - unique identifier of a token, e.g "0x3234235"
        symbol      [string] - token's symbol e.g. "ETH" or "SNT"
        name        [string] - token's name e.g. "Ether" or "Dai"
        icon        [url]    - token's icon url
        balance     [double] - tokens balance is the commonly used unit, e.g. 1.2 for 1.2 ETH, used
                               for sorting and computing market value
        balanceText [string] - formatted and localized balance. This is not done internally because
                               it may depend on many external factors
        error       [string] - error message related to balance

        marketDetailsAvailable [bool]   - specifies if market datails are available for given token
        marketDetailsLoading   [bool]   - specifies if market datails are available for given token
        marketPrice            [double] - specifies market price in currently used currency
        marketChangePct24hour  [double] - percentage price change in last 24 hours, e.g. 0.5 for 0.5% of price change

        communityId   [string] - for community assets, unique identifier of a community, e.g. "0x6734235"
        communityName [string] - for community assets, name of a community e.g. "Crypto Kitties"
        communityIcon [url]    - for community assets, community's icon url

        position    [int]  - if custom order available, display position defined by the user via token management
        canBeHidden [bool] - specifies if given token can be hidden (e.g. ETH should be always visible)
