Useless for tacking crypto. No custom alerts. Values update very slowly and only show to two units of precision (e.g. 0.00). Exchange from/to cash is expensive. Very buggy, sometimes having to press several times on an option for it to register. Sneaky hidden fees - when converting between altcoins, you get charged the spread between the ask and bid prices which doesnt show in the transaction preview. Took me a couple exchanges and a google search to figure out why I was losing $10+ each trade.
