https://www.hashrate.no/gpus/4090The RTX4090 graphics card is very hot and consumes a lot of power.
For these video cards, you need to have 15 kilowatts per hour of free power to provide your rigs with good cooling.
I don’t know if mining with a profit of a dollar per day at 5 cents per kilowatt is profitable for you.
1 dollar for one card is OK in most countries and if it is 30 dollars daily I would take the hassle and trouble to configure,troubleshoot and maintain my rigs.If it is 1 dollar for 30 RTX 4090 then it is not worth,in fact I see now in the very same website if you pay electricity it is only 0.25 dollars profit for one card and so it means 7.5 dollars for 1 day or 225 dollars monthly,well I doubt anyone except in third world countries would take the time and trouble to maintain such hot rigs for such an amount of profit monthly.
Or in a second option people who have no money but have at disposal such cards,they can do it for 225 dollars monthly and diversify such amount in buying different coins that they think have a bright future.
