The current old-school altcoins can generally be divided into two categories:
1. Trend-type (sustained upward movement): These types of coins have relatively stable increases, with multiple adjustments during price fluctuations, providing repeated entry opportunities, suitable for trend-following strategies.
2. Explosive-type (rapid increase in a short time): The price increases of these types of coins are concentrated in an extremely short period, usually with violent fluctuations, lacking mid-way adjustments, and almost no opportunities for mid-way entry, only allowing for breakout chasing.
Examples: UNI AAVE LTC belong to the trend-type, while BCH leans more towards the explosive-type
