If you have assets with transactions, but currently hold zero or very little of that cryptocurrency/asset, don't remove them from your portfolio! That will delete all transactions linked to that asset and it will be as if they were never added. This can mess up your whole portfolio and you will need to go through and re-add the transactions to rectify it.
Instead, if you would like to hide assets with holdings of exactly 0.00 only, enable the 'Hide 0 holdings' option under Settings -> View Options.
If you would like to hide assets with small holdings, enable the 'Hide small holdings' option under Settings -> View Options. At the moment, this hides holdings that are worth less than 0.2% of your total portfolio. We may make this option more customizable in the future.
PRO TIP: If you want to unhide the assets, follow the settings above and untoggle the relevant settings.
PRO TIP 2: If you want to see the transaction history, or add a transaction for the hidden asset, you can find the hidden asset by searching for it with the search function found in the top right of the main portfolio page.
PRO TIP 3: If your portfolio balance is showing incorrectly or not adding up as you think it should, please untoggle the settings above as it may uncover some negative balances. If there are no negative balances, you can reach out to us at email@example.com.
