In the current sensitive market phase, assessing the probability of an altcoin being "pumped" is extremely important.

A simple yet effective observation method is to watch how the altcoin reacts when $BTC makes adjustments. For example, when BTC drops from $76,000 to $74,000, observe how the coin you hold responds:
• If BTC decreases but your altcoin hardly drops, or only adjusts slightly, and even maintains a stable price structure → there is a high likelihood that there is money supporting the price. These cases can continue to be held and wait for the next pump.
• Conversely, if BTC only needs a slight correction but your altcoin "sells off strongly," loses its structure, and quickly breaks support → it’s very likely that large capital has withdrawn. At that point, the risk of being abandoned is very high.
The past two months have been a "last revival" for many weak altcoins. Many projects only have a short window to be pumped and escape liquidation. If during this period there is no clear buying force, then future opportunities are almost gone. Even for projects with weak liquidity, the risk of delisting entirely can occur—and then the price could plummet close to zero.
Note: This "law" mainly applies to small-cap, low-liquidity altcoins that heavily depend on speculative capital flows. For major coins with large ecosystems and liquidity, volatility is usually more cyclical and macro-driven, and cannot be generalized in this way.
In the altcoin market, what matters is not just news or stories, but price behavior during market fluctuations. Price doesn’t lie—new capital is the ultimate determinant.
