Some altcoins are beginning to emerge from the rhythm of a 'small spring' - the overall rebound speed is fast and the amplitude is fierce, giving the impression of great momentum.
In this kind of market, while prices are rising, to establish a trend, a sustained trend, or a reversal market, at least three points must be observed:
1. Clear price structure
2. A large amount of capital continuously entering the market
3. Market sentiment shifting from divergence to consensus
Without these fundamentals, no matter how fierce the rise, it may just be a 'rise and then rest.' Similar to 'lottery-type' small-cap altcoins, a V-shaped reversal can occur, with a 100% increase in one or two days being quite common.
When such opportunities arise, it's good to make a profit easily; if not, don't force it.
