There are time for everything. You should just wait. If you sell it immediately it is not worth it.
I think this should be based on time. If we know that all the altcoins will collapse next, rather than selling it quickly, I think it is unwise.
Of course, if you are a long-term investor, you can ignore the momentary rise and fall.
Its just a matter of decision making, if you think the current price is enough for you and you can earn in what you are selling, then its ok to sell even at an early stage. But if you are talking about long term then you can ignore whatever price in it.
