More patience, less impulse
After buying in a bear market, you need to patiently wait to sell in a bull market; do not make trades during the fluctuations, and the waiting period requires patience.
After selling in a bull market, patiently wait for the bull market to collapse and enter a bear market. This may take one to two years. Do not impulsively try to buy at the halfway up or down the mountain; patiently wait for the moment it falls to the valley bottom.
After making money from selling in a bull market, do not give in to the temptation to impulsively invest in altcoins. If you really want to take a gamble, only use at most 10% of your funds.
