“Coin dust” is referred to all balance asset entries of insignificant value, piling up as a result of trading and getting in the way of relevant data.
The dust filter allows you to filter-out all such irrelevant balance entries. The dust filter is located in the header of your full balance widget.
Turn on the filter and use the slider to set a value limit in USD under which all balance entries will be hidden.
The “dust filter” affects “Shared portfolios”, if you have any. Learn more about “Shared portfolios” further in this section.
