Market fluctuations have such limited space; since last year until now, it has been oscillating within this range. Instead of being led around by the ups and downs of the market, it's better to first clarify your own trading logic.

A simple and straightforward strategy is actually just that—white line position is the key dividing line. If above, go short; if below, go long. Use small positions to avoid being casually swept up by the big players. Many people ask why they can't make money; frankly, it's still about poor position management. Not participating in small trends, and not daring to trade in big trends—this kind of dilemma is the easiest to lose money on.

**On Bitcoin**: as long as it doesn't break below 88,000, keep an eye on resistance levels for shorting. 89,066 and 90,366 are two defense lines; if it really breaks through, watch 90,800. After a pullback, consider going long at 87,388, 86,777, 85,688—final safety net at 85,000.

**On Ethereum**: resistance at 3,028 and 3,077, with a defense point at 3,083. If it can hold steady after a pullback at 2,988, this wave of market might still have potential. If broken, opportunities to go long are at 2,960, 2,916, 2,868, with the final defense at 2,850.

It's easier said than done—every trade must include a stop-loss (Bitcoin 500 points, Ethereum 50 points). This isn't an unnecessary protective measure; it's the bottom line for survival in trading. The market never lacks opportunities; what it lacks is the right mindset and discipline. If there's a sudden break or a key level is breached, you must immediately reassess and not stubbornly cling to the original strategy. Maintain respect for the market and flexibility with your positions—that's the key to long-term stable profits.
