General opinion is that a side job is one that supports the main income of an individual, often times perceived as something that brings little money to add to what you make from your day job. If Mr X earns better from a side job when compared to the income from his career option, does the side job still qualify to be called a side job?
Still it is a Side Job No matter and how much you are gaining from it . because your main job is the stable one while your side job is sometimes profiting and sometimes not.
like me, My main job brings me fix earning monthly while my side job here in crypto(like trading and some staking in gambling sites) brings me more than what i earn per month.
but still i called it side jobs.
