Trading is unpredictable so should be have some trading plan, strategy and risk management, my strategy is wait patiently to get cheap price or in the bottom when buy and sell partly when taking profit. Dont forget use cut loss strategy when any bad news. Become expert trader need times and process so always patient for that.
besides, make a strategy, you need to control yourself and don't become greedy if you can sell and make a profit because the chance to make a profit cannot predict too. so it is better to take the profit while we can and then we can wait for the price to go down so we can buy the coin with cheap price. but the patient is the difficult things that we should do because not all people can be patient to wait the price is up and down.
