Trading and buying to hold are two different things. You need the basic guides of trading to be a holder, but trading requirements go above the things you suggested above. The list you also provided is a part of the trading guide, but it serves more as a preference list for someone looking to buy a coin to keep. To survive as a trader, you need to have things like a trading guide, the basic indicators, you need to understand the trend, support and resistance, the candle, how to overcome media manipulation and the games of whale and market maker, and many more if you want to go dip in trading.
