Indeed! Day trading is generally related to altcoins, all those coins that are just starting their journey in the crypto market.
I don't think your generalization holds water, what determines what coin to Hodl is their stability overtime and future projection. Presently I am Hodling Dogecoin (21 Satoshi today) rest assured that I shall be selling them at 100 Satoshi or more in the not too distant future!
Day trading is very much hectic and people definitely dont like much getting into day trading.
Yes day trading may seem like Latin to an English man because he actually knows next to nothing what it is all about!
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.
Bitcoin happens to be one of the most volatile currencies, so easy to be down or up by over 500 USD within 24 hours. Then reason people nonetheless Hodl it, is because of the very strong community bias and projection that Bitcoin is headed for the moon, of which it has corroborated time and again by its resilience in bouncing back every time it ran into a storm.
It depend on people that what type of people they are because if you are talking about bias then nothing is like that it doesnt concern to bitcoin because bitcoin having own place while other things having not so we should not say something like this because it is all depended on people so I would like to say that we should follow our rules instead other.
