Many common beliefs in this circle are wrong.

For example, many people think that laying out positions in a bear market leads to getting rich in a bull market.
This sentence is incomplete; the complete version should be:
"Lay out BTC spot positions in a bear market to get rich; lay out altcoins to lose everything."

A bear market is not simply a decline.
The bear market that occurs every four years in the crypto space is actually a butcher's knife that kills all contract traders, both long and short, wipes them out, flips the table, and then creates a new gambling table.
Only newcomers who arrive later and the old-timers who survive are qualified to sit at the new table.
All contract traders die, all spot altcoins die.
Only those who buy more BTC spot as it falls survive.
This is the truth of the crypto bear market.

Many common sense statements are half-truths; following them will naturally lead to losing everything.
