In the cryptocurrency world, long and short positions are never simply black or white; they are a matter of probability assessment. You learn the technology, watch the indicators, manage risks, just like a captain learns to row, looks at the compass, and controls the sail—yet the sea always has winds and waves, and the market always has surprises.
Excellent traders are not those who are never overturned by the waves, but those who know when to furl the sails and avoid risks, when to take advantage of the situation, and more importantly, which "seas" should never be ventured into.
No one can always return with a full load, but the old captains who survive can always seize opportunities in the next tide. The market rewards patience and discipline, not blind confidence.
