I think grouping tokens based on the niche they belong can answer the question "what coin should I trade at the particular moment in time" as it helps to filter the noise and know where the entire market is focusing on.
fortunately coingecko and coinmarket cap has this list and it's always a good place to give me hint on what crypto should i trade at the time being.

just looking at market cap change and price change for the last 7 days enough to give me insight on what's the altcoin that has bigger chance to have higher volatility and also higher chance of pumping.
but I personally always prefer to ride the hypes, trying to find hidden gem before it's showing its real worth.
