For the next market, buy at a place where no one cares, and do whatever you want before you achieve financial freedom. Making money is always your top priority. Sell when there is a lot of noise, don't have any nostalgia, always be fearless of selling high, selling high is the way to make long-term profits. When the market starts to get busy, everyone starts shouting to buy blindly, all kinds of experts come out to show off, the fear and greed index reaches a new high, news media advertisements are everywhere, and Google search index explodes. At this time, leaving this market will never be wrong.
