Day trading or holding has the same risk and can both get profit, for day trading it requires more knowledge and deeper skills, because it regulates financial patterns in trading. while for holding only need to hold and save until the price is high. so it's a choice based on one's ability
Both are risky and will depend on us if we can determine the price or predict whether it has a future in it.
