My only advice, just ride the trend. Market is unpredictable and we don't have ability to predict the exact same thing to happened.

Come on. Doing crypto trades isn't easy as you think. People who earned a lot here not always win in terms of luck. They analyzing the market to win the game. Price decrease is possible since it's impossible that the trend will always be going up. No way it will happen since people are eyeing for the profits. And don't see price decrease as bad happenings. During price decrease it's a big chance for people to buy again at lower price then just wait again for the increase for possible profits.
