Discontinuing support of a particular coin can happen. If this does occur, Abra will notify users who hold those coins via the email linked to that wallet.
Abra will make every attempt to notify our users of the discontinuation of a coin as soon as we are aware of the change.
Once the discontinuation date has occurred, those assets will no longer be supported.
If Abra were to discontinue a coin such as PinkCoin (PINK), once the discontinuation date has occurred you will no longer be able to deposit, exchange, or withdraw PinkCoin (PINK). You will lose the balance you carried in PinkCoin (PINK) if you do not exchange or withdrawal those assets prior to the discontinuation date.
