Day traders are just trying to make a quick buck.  They try to buy on downs and sell on ups.  This works if you have a lot of money to move markets and bots to do it.  Also works if you have really good intuition or insider info.

I'm a long term holder and I buy when an asset has regularly gone up and I feel like in the future there will be more reason for it to go up.

I don't day trade because there are big day traders looking to eat you up.
