In the face of extreme fluctuations caused by sudden news, panicking is the least useful response. Staying calm is the only correct choice:

① Have some spare positions

Don't go all in! Leave some bullets to deal with the unexpected.

② Distinguish the source of information

Don't be scared silly by headlines; some 'sensational news' actually lacks solid evidence.

③ Set profit-taking and stop-loss in advance

When the market moves, stay calm and execute according to the plan; emotions should not interfere with judgment.

④ Don't go all in

Avoid going ALL IN on a single cryptocurrency; diversifying is safer.

⑤ Reduce frequent operations

The more volatile the market, the more restraint is needed. Impulsive trading often marks the beginning of losses.
