Old-fashioned altcoins can be roughly divided into two categories:

1. Trend type (the rise is continuous): The rise of this type of currency is relatively stable, and there will be multiple adjustments during price fluctuations, providing opportunities for repeated entry, which is suitable for trend following strategies.

2. Explosive type (rapid rise in the short term): The price increase of this type of currency is concentrated in a very short period of time, usually with violent fluctuations, lack of mid-term adjustments, and almost no opportunity to enter the market midway, so it can only be a breakthrough to chase the rise.

For example: $NEAR belongs to the trend type, while BCH and $XRP are more inclined to the explosive type.
