HTS's Wallet Asset feature allows you to visualize the contents of all of your crypto-currencies and fiat amounts across all of the exchanges that HTS is connected to. This is valuable for traders as it allows them to visualize the assets across all of the exchanges, on a single page.
To use the wallet asset, you must be connected to the exchange. As you hover across the graphics, more details about the contents of your wallet will be shown. Below is a screenshot of what the entire Wallet Asset page looks like.
