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. How do you do yours?
When you trade, trading volume, available liquidity are most important to consider. Because if you only can enter but can not exit or get big loss by price slippage as consequence of low trading volume, low liquidity, it's not your job to start trading at all.
After see good trading volume, liquidity, it's time for you to look at a more important factor, fundamentals of that project. With good fundamental projects, if you trade wrongly, you still won't lose all your money.
A most safest cryptocurrency for trading is not any token, but Bitcoin. Highest trading volume, longest survival time so far, no rug pull.
Tokens? They are very risky and I don't recommend people to focus on trading with tokens.
