In this market, after years of experience, I have summarized a few iron laws that must be followed.

First, stay away from those low-heat altcoins, especially projects controlled by a few people—these can wipe you out with just a slight fluctuation. Second, be ruthless with stop-losses; many people lose money waiting for "just a little longer to break even," only to see their situation worsen. When facing losses, don't argue with yourself—accept the loss and move on. Don't let emotions dictate your decisions.

Position management must be strictly enforced. Greed is the biggest killer in this industry—no matter how good the opportunity, control your size. Set a stop-loss for every trade; take profits promptly when winning, and review losses to find issues. There is only one chance to add positions—whether your judgment is right or wrong, this is the only opportunity. Don't hold onto false hope.

Honestly, only Bitcoin can truly carry you through bull and bear cycles. Other coins, no matter how hyped, are just supporting roles. Losses are not the scariest part—what's most frightening is staying up late, wrecking your health, and not making any money. Take good care of your body; this is a cost worth paying.

Finally, you need faith. Not blind faith, but a conviction based on rational analysis. Only then can you avoid being scared out of the market during fluctuations.
