Let me support you. The market is ready to open the door to the green zone. It was on the bottom many months, and now most of the coins will start to gain. That is why it is better to hold.
Also selling now will not make any senses as those who have bought at higher rates will sell in a loss and then when market recovers they would feel so bad that they lost the money making opportunity. SO rightly said unless you require money then only sell it else keep holding and buy more.
