Project team: To do a project, it is necessary to have a grand narrative and imply rich profit expectations, otherwise retail investors will not buy, no one will buy, and they will not be able to make money We ourselves: When doing trading, don't believe in any grand narratives, don't believe in others' self praise, share historical records, or analyze trends for weeks at a time (see today's and tomorrow's trends clearly before speaking, keep shouting for a daily rebound, from 100000 to 80000 is also impossible).
