1$ every hours is 24$ per day, the best way to make this works out is building a mining rig yourself with high end cards, will cost you some money though but that exact amount can be earned every single day, if you are interested go to YouTube and watch several videos about how to setup a mining rig
I haven't thought of this but you're right. Mining through video card will allow you to earn every hour. But it wouldn't be $1 per hour as I've checked some calculators like through nicehash with the most high end RTX version which is 3090.
Computation per day is a gross of $9 and if you'll less the consumed electricity for example is $0.3/kwh, you'll get $7 per day. Not that bad if you have many of it and works at the same time. In less than a year if the market's status is still the same, you're already in ROI.
It is a costly source but it's profitable if you've got the highest end cards.
