In my opinion you can do both day trading and holding. Day trading is mostly for coins that pump and dump.
For those coins that have potential in the long term can hold for a longer period.
Indeed! Day trading is generally related to altcoins, all those coins that are just starting their journey in the crypto market. Day trading is very much hectic and people definitely dont like much getting into day trading. But still if your coin fluctuates a lot in prices, you are eligible for day trading but coin like bitcoin generates best results when held for long time.
