As the holdings, altcoin values fluctuate continuously, you can arbitrarily choose to sell at reasonable prices, in short sometimes the price is not high but you sell them in a hurry you will lose and regret it.
Although it is less profitable. However, in my opinion, it is less profitable, but if you buy and sell continuously during the day, it will make more profit than you keep. In case if the market does not increase but goes down, you get profit if you keep?
