Do withdrawals really come “instantly” or is that just marketing bs?

i keep seeing crypto sites flex “instant” withdrawals but i’ve never actually had one hit my wallet that fast. quickest i got was like 5 mins and that felt like luck. usually i’m staring at a pending screen for way longer than their banners claim, especially late at night. maybe depends on the coin or network? or just straight up hype for promo. slots wins seem to trigger slower checks too, while poker cashouts sometimes just need one extra confirm.

is anyone actually getting these “instants” every time, or is it just hit or miss? wondering if i’m just impatient or if there’s a legit method to speed these up.
