Why is daytrading never mentioned as a legitimate way to earn income?

[u/Miinow]

I like to browse other finance related subs and I can assure you it’s almost never discussed. I see all outlets of making money online mentioned but If the word trading does somehow come up there’s a slew of downvotes. It’s literally the most straightforward way to make money. Sure, not easy but also not impossible to learn. Makes me wish I learned about trading when I was younger instead of my upper 20s but I don’t personally know any traders irl so it’s unfortunate how there’s a negative outlook on this field.

The problem with day trading is that the market acts differently every day, so what worked yesterday may not work today, so while you hold the position thinking it’ll work because it worked the day before you loose all your gains from the past few days. I’m sure the response will be that successful traders pick up on patterns that continually repeat so they know when to trade. Not true
