Because social media is highly developed and widely spread,

all financial instruments have effectively had leverage increased.
A bad piece of news will make assets fall rapidly,
and a good piece of news will also make assets surge quickly.
Coupled with various quantitative methods and insider information,
the complexity of short-term trading—and the probability of losing money—have both increased.
All analysis is built on a set of assumptions made by individuals.
Only your own profit and loss is the best answer.
Buy when no one is paying attention, sell when the crowd is buzzing—
this is an eternal principle!
