The deeper the loss, the harder it is to turn around—this is the most heartbreaking math problem in the crypto world.

Many traders only think about "doubling up in one shot," but they don't consider a harsher reality: principal is the foundation of everything.

Warren Buffett's investment philosophy applies equally to the crypto market: First, don't lose money; second, always remember the first rule.

Look at these numbers and you'll understand:

Losing 10% requires an 11% gain to break even; losing 30% requires a 43% gain; losing 50% requires doubling; losing 70% requires a 233% increase to have a chance to turn around.

Do you see the pattern? The more you lose, the greater the cost to recover. Small losses can be made up through subsequent trades, but if the account is halved, it's basically over.

So, stop-loss isn't a technical issue; it's a survival issue. Those who last longer in trading are often not the ones who earn the most, but those who are best at admitting mistakes and cutting losses. As long as the account stays alive, opportunities are always there. As long as it hasn't gone to zero, there's always a chance to turn things around.

Don't stubbornly hold onto losing positions that are already going bad. Cutting losses in time may seem like "giving up," but it's actually leaving chips for the next market move. Keep your account stable, and you'll have the capital to seize real big opportunities. Lasting longer is much more important than making quick money.
