You shouldn’t be asking that question. Whether to buy, hold or sell is a decision that you will make by yourself. You don’t need anyone to tell you that you’re supposed to HODL or sell, it’s a  decision you can take by yourself. You know when you’re making loss and when you’re profit. If what you’re making is loss, you can decide to cut it short by selling off immediately to avoid further loss and wait till price starts going up. But if you’re making profit and there isn’t much loss, then you can continue to HODL till you feel like you’ve gotten enough.
