After experiencing 519, my biggest understanding is that only gradual realization is real, and letting my family live a better life is real. Keep a certain amount of principal in the currency circle, bet small on big, look for top opportunities, and wait patiently. The fur will not end, the dog will not end, and the story will not end. What ends are the people who come in and out.
Always be in awe of the decline, and always pursue the sudden wealth effect of the currency circle. The story will not end until you quit the circle.
