Recently, one must be cautious when shorting old altcoins on Binance; it has become noticeably harder to make a profit.

Some low-quality altcoins are starting to pump, likely because they fear being delisted from Binance, and also because they have indeed dropped very low. If the whales are still around, their cost for accumulating tokens is low. If there are many people shorting, they can push the price up to squeeze shorts and still make a profit.

From a psychological perspective, the whales of small altcoins have the advantage.

Because the downside has limited space, the shorts can make at most 1x profit; however, if the price is pushed up and the whales have strong control and capital, they can indeed pump it several times or even ten times, leading to significant losses for the shorts.

So either wait for a fierce short squeeze to open a position, or find a seemingly strong whale to open a long position closely, but if there are too many people riding the wave, one must be careful that the whales might take the opportunity to cash out.
