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?
Professional traders don’t depend on one coin in the market. As a trader, all you need to know is how the market works or how the coin you want to trade on at that time moves in the market. But if you depend on a specific coin that you will be trading all the time, you are going to be at a loss all the time.
As a trader who really wants to make money out of trading, you need to study many coins and know how the market moves so that anytime you enter the market, you will know the steps to take and make your money, so don’t depend on a coin. I can see that you still want to learn because the way you ask the question suggests you still want to know more about trading in general, so go and learn before entering the market.
